Parents’ Guide to A-Level Biology Tutoring
Written by a Chartered Biologist and former examiner with over 25 years of A-Level Biology teaching experience. Everything you need to know about supporting your child, understanding the exams, and deciding whether tutoring is the right step.
Last updated: February 2026
Why I Wrote This Guide
In over 25 years of teaching A-Level Biology, I’ve had hundreds of conversations with parents. The same worries come up again and again: “My daughter got a 9 at GCSE but now she’s getting Ds — what’s gone wrong?” or “He wants to study Medicine but his grades aren’t where they need to be.”
I understand the anxiety. A-Level Biology is a high-stakes subject. It’s the gateway to Medicine, Dentistry, Veterinary Science, and dozens of other careers — and the jump from GCSE catches a lot of families off guard.
This guide is everything I wish I could sit down and explain to every parent. Not a sales pitch, but honest, practical advice from someone who has taught this subject in classrooms, marked thousands of exam papers as an examiner, and helped students across every UK exam board turn things around.
You don’t need to understand ATP synthase or the Calvin cycle to support your child effectively. You just need to know what to look for, when to act, and what questions to ask. That’s what this guide is for.
Why A-Level Biology Is Different from GCSE
The transition shock — what parents need to know
This is the single most common issue I see, and it catches even the brightest students off guard. At GCSE, Biology rewards students who can recall information and explain it in general terms. At A-Level, the game changes completely.
The content volume roughly doubles — yet both courses run for two years. Mark schemes demand precise scientific terminology: if your child writes “glucose breakdown” but the mark scheme requires “glycolysis,” they get zero marks for that point. At least 10% of all marks require maths at A-Level standard, including statistics, logarithms, and data analysis.
I see this pattern every year: a student who comfortably achieved grades 8 or 9 at GCSE starts getting Ds and Es in their first Year 12 assessments. Their confidence collapses. They start thinking they’re “not good enough” for Biology. In reality, they’re just experiencing the transition shock — and it’s completely normal.
Topics your child will find hardest
After 25 years of teaching and examining, I can predict with reasonable confidence which topics will cause problems. These are the ones that generate the most panicked calls from parents:
- Photosynthesis — light-dependent and light-independent reactions involve multi-step biochemistry that requires precise sequencing
- Cellular respiration — glycolysis, Krebs cycle, and the electron transport chain overlap in confusing ways, with similar-sounding terminology
- Genetics and inheritance — epistasis, linked genes, and chi-squared statistical tests push students well beyond GCSE-level
- The immune system — complex multi-step processes with specific cell types and functions to distinguish
- Protein synthesis — transcription and translation are conceptually abstract and sequence-dependent
- Synoptic questions — these require students to link knowledge from across the entire specification, which many find overwhelming
The common thread? These topics involve complex, multi-step processes where each step depends on understanding the previous one. Miss one piece and the whole chain breaks down. That’s precisely where a specialist tutor can make the biggest difference — rebuilding the chain from whichever link broke.
How to Know When Your Child Needs a Tutor
Warning signs to watch for
You don’t need to understand the subject to spot when things aren’t going well. After working with hundreds of families, these are the patterns I’ve learned to recognise — and that you can look out for at home:
Grades Dropping
Test or mock results falling below target, especially a sudden drop from what they achieved at GCSE.
Avoidance Behaviours
Not wanting to discuss school, hiding test results, or consistently procrastinating on Biology homework.
Loss of Confidence
Phrases like “I’ll never understand this” or “everyone else gets it” — especially from a child who was previously confident.
Frustration with Marks
“I knew the answer but still got zero.” This usually points to exam technique problems — knowing the biology but not how to write for marks.
The best time to start tutoring
I’ll be straightforward: the best time to start is at the beginning of Year 12. Building strong foundations from day one prevents problems from developing and is far less stressful than crisis intervention close to exams.
That said, the most common points when parents contact me are after disappointing January mocks (Year 12 or 13), or at the start of Year 13 when exam pressure suddenly feels real. Both of these are perfectly fine starting points — there’s genuinely always time to improve if the support is right.
What I’d gently caution against is waiting until April or May of Year 13 and expecting a miracle. I’ll always be honest about what’s realistically achievable in the time available.

Qualifications that actually matter
The tutoring market ranges from university students charging £15 an hour to specialist agencies charging over £100. The question every parent should ask is: what am I actually paying for?
Not all tutors are equal, and price alone doesn’t tell you much. Here’s what I’d recommend you look for, in order of importance:
Parent’s Checklist for Vetting a Biology Tutor
- Enhanced DBS check — self-employed tutors in the UK have no legal requirement for one, so always ask
- Relevant degree in Biology or a closely related discipline (not just “science”)
- Teaching qualifications — QTS, PGCE, or substantial tutoring experience with A-Level students
- Board-specific expertise — they should know your child’s exam board inside out
- Examiner experience — understanding mark schemes from the inside is a significant advantage
- Professional recognition — Chartered Biologist (CBiol MRSB) is the gold standard for professional standing
- Verified reviews — look for specific outcomes, not just “great tutor” on their own website
Why examiner experience makes the difference
This is something most parents don’t think to ask about, but it makes an enormous difference. When I marked papers for WJEC/Eduqas and Edexcel, I saw thousands of students lose marks not because they didn’t know the biology, but because they didn’t know how to write for marks.
A-Level Biology mark schemes are incredibly specific. A student might write a perfectly reasonable answer that demonstrates genuine understanding — and score zero because they used the wrong phrasing. As a former examiner, I know exactly what the mark scheme is looking for and can teach students how to write answers that actually collect those marks.
DBS checks and safeguarding
This is important, so I’ll be direct. In the UK, self-employed private tutors have no legal requirement to hold a DBS check. Unlike schools and colleges, the private tutoring industry is largely unregulated. Always ask to see a tutor’s DBS certificate before sessions begin, and verify it’s current — ideally registered on the DBS Update Service for continuous verification.
Understanding Exam Boards: AQA, OCR, Edexcel & WJEC
Your child’s school will have chosen which exam board they use, and you probably haven’t given it much thought. But the differences between boards are significant — different exam structures, different content emphases, different marking styles. A good tutor should be tailored to your child’s specific board.
| Exam Board | UK Share | Key Features | A* Boundary (2024) |
|---|---|---|---|
| AQA | ~55% | Most popular. Includes a unique 25-mark synoptic essay in Paper 3. Mark schemes are notoriously strict. | 74% (192/260) |
| OCR A | ~15% | Most content-heavy specification. No essay. Generally more straightforward exam questions. | 69% (187/270) |
| Edexcel A (Salters-Nuffield) | ~25% | Context-based approach with unfamiliar scenarios. Often considered the trickiest by students. | 66% (199/300) |
| WJEC / Eduqas | ~5% | Dominant in Wales. Uses extended-response QER questions requiring structured scientific writing. | Varies by unit |
Grade boundaries — what they mean
Grade boundaries change every year and vary between boards. In 2024, AQA’s A* boundary rose from 69% to 74% — a substantial jump that caught many students off guard. This is why I always tell my students to aim for a comfortable margin above the expected boundary, not just scraping through.
Biology consistently has the lowest A*/A rate among the three main sciences (27.6% vs 32% for Chemistry and 31.9% for Physics in 2025). This doesn’t mean it’s the “hardest” science, but it does reflect that Biology attracts a very broad range of students — making the competition for top grades genuinely fierce.
How Tutoring Improves A-Level Biology Grades
What the evidence says
I know tutoring is a significant investment, so I’ll share the independent evidence rather than just asking you to take my word for it.
The Education Endowment Foundation (EEF) — the UK’s leading independent education research body — found that one-to-one tuition provides approximately five months of additional academic progress. That’s a substantial impact, equivalent to moving a student from a D to a C, or a B to an A, depending on their starting point.
Their research also found that the impact is the same whether tutoring is delivered online or face-to-face. Short, regular sessions — around 30 minutes, three to five times per week over 10 weeks — deliver the best outcomes. That said, most of my A-Level students do well with weekly one-hour sessions, supplemented by targeted work between sessions.
Online vs in-person — which works better?
Multiple studies now confirm there is no meaningful difference in academic outcomes between online and in-person tutoring. I teach all my sessions online, and I can tell you from experience that it works brilliantly for A-Level Biology. Here’s why:
- Interactive whiteboards let me draw biological diagrams in real time — just as I would on a classroom board
- We can share screens to work through past paper questions together, side by side
- Sessions can be recorded so your child can rewatch explanations before exams
- No travel time means sessions fit around school, activities, and other commitments
- Your child gets access to a specialist tutor regardless of where you live in the UK
How many sessions does your child need?
There’s no one-size-fits-all answer, but here’s how I typically advise parents:
- Foundation building (Year 12): One session per week alongside school lessons, focusing on understanding and exam technique from the start
- Catch-up or confidence rebuilding: One to two sessions per week for 6–8 weeks, then reassess
- Pre-exam intensive (Year 13, Feb–May): One to two sessions per week focused on past papers, mark scheme technique, and targeted topic revision
- Specific topic rescue: Sometimes 3–4 focused sessions on a single topic (like photosynthesis or genetics) is all that’s needed
I’ll always give you an honest assessment in the free consultation. I’d rather tell you your child doesn’t need a tutor than take your money when school support would be enough.
A-Level Biology and University Entry
For many parents, the real pressure behind A-Level Biology isn’t the subject itself — it’s what it leads to. If your child is aiming for Medicine, Dentistry, Veterinary Science, or any competitive biological science degree, the grades they achieve in Biology directly determine which doors open.
Requirements for Medicine, Dentistry, and Veterinary Science
Medicine: Standard offers range from AAA to A*A*A depending on the university. Around 15 UK medical schools require both Chemistry and Biology. However, 9 medical schools — including Oxford and Cambridge — don’t formally require Biology, though they strongly recommend it. The most popular A-Level combination for aspiring medics is Biology + Chemistry + Maths, taken by over 18,500 students in 2025.
Veterinary Science: Almost all vet schools require both Biology and Chemistry at grade A. Standard offer: AAA. The UCAS deadline is 15 October (the same early deadline as Oxbridge and Medicine).
Dentistry: Nearly all dental schools require Chemistry and Biology, with grades typically from AAA to A*AA. Competition is fierce, with roughly 15 applicants for every place.
Biomedical Sciences: Russell Group universities typically require AAB to AAA including Biology. Many other excellent universities accept BBB.
The practical endorsement (CPAC) explained
This is something very few parents know about, but it matters. Alongside their A-Level grade, your child will receive a separate pass or fail for their practical endorsement (called CPAC). This is assessed by their school teachers through direct observation of at least 12 practical activities.
The practical endorsement appears on the certificate alongside the overall grade. Some competitive courses — including Medicine at certain universities — explicitly require a pass in the practical element as part of their offer conditions. If your child has missed practicals due to illness, make sure you understand the school’s catch-up process.
How Much Does A-Level Biology Tutoring Cost?
I believe in transparency about pricing. Here’s an honest breakdown of what you can expect to pay across the UK market:
University Student
Marketplace platforms like Superprof. Usually recent graduates. Variable quality and exam board knowledge.
Platform Tutor
MyTutor, Tutorful. Mix of students and teachers. Platform handles DBS. Average ~£40/hr for A-Level.
Specialist Examiner
Chartered Biologist. Former examiner. 25+ years experience. All exam boards. Board-specific exam technique.
Premium Agency
The Profs, Minerva. Opaque pricing. Often use subcontractors. You may not know your tutor’s credentials upfront.
What drives the price differences?
The biggest factor is expertise. A university student who achieved an A* last year knows the content — but they don’t know why students lose marks, how examiners think, or how to diagnose where understanding breaks down. A qualified teacher with examining experience brings a fundamentally different level of insight.
I charge £80/hr on weekdays and £120/hr on weekends for one-to-one sessions. For families who’d prefer a more affordable option, I also offer small group sessions at £50/hr weekday or £80/hr weekend per student (minimum 4 students). Every engagement starts with a free 20-minute consultation so we can discuss your child’s specific situation before any commitment.
How You Can Support Your Child at Home
You don’t need a Biology degree to make a real difference. Research consistently shows that parental support around organisation, wellbeing, and motivation has a significant impact on A-Level outcomes. Here’s what actually helps:
Practical things you can do
- Ask them to teach you a topic — this is genuinely one of the most effective revision techniques. If they can explain the Krebs cycle to you in plain English, they understand it properly.
- Help with organisation, not content — revision timetables, folder organisation, and making sure they have the right resources are all things you can support without needing subject knowledge.
- Protect their sleep — 8 to 9 hours is ideal. Late-night cramming actively damages memory consolidation and makes the next day’s learning less effective.
- Keep phones out of study spaces — research shows that a phone’s mere presence (even face-down, even turned off) reduces cognitive performance by roughly 20%.
- Watch for burnout — changes in sleep patterns, irritability, loss of interest in hobbies, and persistent fatigue are signs your child needs support, not pressure.
Things to avoid
I say this gently, because every parent I’ve met is acting from a place of genuine care: avoid comparing them to other students, avoid “when I was your age” conversations about study habits, and resist the urge to hover over their revision. The student needs to own their learning — your role is to be the safety net, not the driver.
How I Can Help Your Child
I’m Tyrone — a Chartered Biologist, former WJEC/Eduqas and Edexcel examiner, and A-Level Biology specialist with over 25 years of teaching experience. Biology isn’t just my profession; it’s my lifelong passion. I hold a BSc in Immunology from King’s College London and a research degree in Molecular Pharmacology from Newcastle University.
I spent 18 years teaching A-Level Biology at Gower College Swansea — one of the top-performing sixth form colleges in Wales — before transitioning to full-time private tutoring. This wasn’t a retirement decision. I did it because I wanted to help students across the UK, not just those who happened to sit in my classroom.
I teach A-Level Biology exclusively. No GCSE, no other subjects. This means every hour of my professional development, every resource I create, and every exam paper I analyse is focused entirely on helping A-Level Biology students achieve the best grades they’re capable of.
I cover all UK exam boards — AQA, OCR A, OCR B, Edexcel A (Salters-Nuffield), Edexcel B, WJEC, and Eduqas — as well as Cambridge International and IB Biology. Whatever board your child’s school uses, I know the specification, the mark schemes, and the examiner expectations inside out.

Rates vary significantly depending on the tutor’s qualifications and experience. University students on marketplace platforms typically charge £15–£25/hr. Mid-range platform tutors (MyTutor, Tutorful) charge £26–£50/hr. Qualified teachers and specialist examiners charge £50–£120/hr. Premium agencies can charge up to £180/hr. I charge £80/hr on weekdays and £120/hr on weekends for 1-to-1 sessions, with group rates also available. Online sessions are generally around 20% cheaper than in-person across the market.
Yes — it’s a significant step up. The content volume roughly doubles, mark schemes demand precise scientific terminology rather than general understanding, and at least 10% of marks require A-Level standard maths. Students who achieved grades 8 or 9 at GCSE commonly find the first few months challenging. This is a well-known transition and doesn’t mean your child has chosen the wrong subject — it means they need to adjust their study approach.
Look for a noticeable drop from target grades (especially after mocks), avoidance of discussing Biology schoolwork, loss of confidence (“I’ll never understand this”), struggling with the transition from GCSE despite good prior results, or frustration with losing marks despite “knowing the answer.” If you’re unsure, I offer a free 20-minute consultation where I can give you an honest assessment.
The independent evidence is strong. The Education Endowment Foundation found that one-to-one tuition provides approximately five months of additional academic progress, with the same impact whether delivered online or face-to-face. The key factors are tutor quality, consistency, and starting before problems become entrenched. Industry data from Tutorful shows 90% of students improve by at least one grade.
Most UK medical schools require Biology at A-Level — around 15 require both Chemistry and Biology. However, 9 medical schools (including Oxford and Cambridge) don’t formally require Biology, though they strongly recommend it. Standard offers range from AAA to A*A*A. The most popular A-Level combination for Medicine applicants is Biology, Chemistry, and Maths. I’d recommend checking specific university requirements on UCAS, as they can change year to year.
AQA is the most popular board (~55% of UK entries) and features a unique 25-mark synoptic essay. OCR A has the most content but more straightforward exam questions. Edexcel uses a context-based approach with unfamiliar scenarios, which many students find the trickiest. WJEC/Eduqas uses extended-response QER questions. Universities treat all boards equally — an A* carries the same value regardless of board. I cover all of these and tailor my teaching to your child’s specific specification.
Multiple studies confirm no meaningful difference in outcomes between online and in-person tutoring. The EEF found the same five months of additional progress regardless of format. Online tutoring offers practical advantages for A-Level Biology: interactive whiteboards for diagrams, screen sharing for past papers, session recording for revision, no travel time, and access to specialist tutors nationwide. All my sessions are delivered online.
Look for a relevant Biology degree, teaching qualifications (QTS or PGCE), an enhanced DBS check, and ideally examiner experience with your child’s specific exam board. The gold standard for professional recognition is Chartered Biologist status (CBiol MRSB) from the Royal Society of Biology, which requires demonstrated competence, commitment to continuing professional development, and adherence to a professional code of conduct.
Based on my 25 years of teaching and examining, the most commonly challenging topics are: photosynthesis (light reactions and the Calvin cycle), cellular respiration (glycolysis, Krebs cycle, electron transport chain), genetics and inheritance (especially epistasis and chi-squared tests), the immune system, protein synthesis, and gene technologies. These all involve complex multi-step processes requiring precise scientific terminology.
The ideal time is the start of Year 12, building strong foundations from day one. The most common starting points are after January mocks or at the beginning of Year 13. Early intervention is always more effective and ultimately less expensive than crisis tutoring before exams. That said, I’ve helped students make meaningful improvements even starting in the spring of Year 13 — it just requires more intensive support.
