Google ★★★★★Tyrone was a great tutor and increased our son’s confidence in tackling the A’level biology exams so that he ended up getting a higher grade than he’d been predicted. It was easy to book tutor appointments, with plenty of availability. Would definitely recommend Tyrone.
Google ★★★★★Choosing a tutor is a big decision. We struggled to find the 'right' biology A level tutor for our daughter. There is a big difference between tutors who can teach/reinforce content and tutors who can teach your student to dissect an exam question, allocate the marks and get the marks every time... ...
Google ★★★★★The best biology tutor, if you are trying to do well in your studies, make sure to give Tyrone the time of day, amazing person, extremely patient and very good at making you understand. I’m a pretty hard person to leach cause I’m real lazy so I promise you he’s really good.
Google ★★★★★Tyrone was an amazing tutor, who helped me so much with A Level Biology when I was struggling with the content in Y13. I liked the way that he explained each topic thoroughly, at a good pace and he always asked me if I had any questions before continuing to teach me, as I felt that the way that the ...

Read QER Guide →How I Help WJEC Biology Students
My approach to WJEC Biology tuition is built on first-hand experience — both as an examiner and as a teacher who delivered this specification every day at Gower College. Every session is tailored to your specific needs, but the foundation is always the same: deep knowledge of the WJEC specification and mark schemes.
Examiner-Led Teaching
As a former WJEC examiner, I teach you exactly what the mark schemes reward. I have marked thousands of papers and I know the specific language, structure, and level of detail that examiners expect. This is insight you cannot get from any textbook.
QER Answer Coaching
Quality of Extended Response questions are where most WJEC students lose marks unnecessarily. I teach you a clear, proven structure for QER answers that consistently earns top-band marks — because I know exactly how these answers are assessed. Read my free WJEC/Eduqas QER Student Guide to get started.
Past Paper Practice
We work through real WJEC past papers together, with detailed feedback using actual mark schemes. I explain not just what the correct answer is, but why other answers lose marks — and how to avoid those same mistakes.
Unit 5 Practical Preparation
The WJEC practical examination (Unit 5) is unique to this specification. I prepare my students thoroughly for experimental design, data analysis, and the written communication required under timed conditions.
Tuition Options
One-to-One Tuition
Individual sessions typically lasting one hour, tailored entirely to your needs. Ideal for focused, personalised attention on the WJEC topics and exam techniques that matter most to you.

Learn more →What Makes WJEC A-Level Biology Challenging
The WJEC specification is the primary A-Level Biology course for students in Wales. Having taught it full-time and examined for WJEC, I know exactly where students struggle — and more importantly, I know how to fix those struggles quickly and effectively.
Common Struggles I Help WJEC Students Overcome
QER (Quality of Extended Response) Questions
WJEC uses banded marking for extended responses. Your answer is assessed holistically against level descriptors, not point-by-point. Most students do not understand how this works — as a former examiner, I do. I teach you the exact structure and language that hits the top band every time. For a detailed breakdown of how QER questions work and how to answer them, read my free QER Student Guide.
Unit 5: The Practical Examination
Unique to WJEC, this timed practical exam tests experimental design, data collection, analysis, and evaluation. Many students underestimate this paper. I prepare my students to approach it with confidence and a clear strategy.
Unit 4: Variation, Inheritance and Options
The genetics and inheritance content in Unit 4 is challenging, and students must also study an option topic. I help students navigate both the compulsory content and the option, ensuring they are fully prepared for this demanding paper.
Biochemistry: Photosynthesis and Respiration
The detailed biochemistry of the light-dependent reactions, Calvin cycle, glycolysis, and Krebs cycle trips up many students. I break these processes down into clear, manageable steps and link them to the specific exam questions WJEC asks.
Mathematical Skills and Data Analysis
WJEC requires a minimum of 10% mathematical skills across the papers. Students need confidence with statistical tests, calculations, and data interpretation. I build these skills alongside the biology content.
Understanding the WJEC A-Level Biology Exam Structure
WJEC A-Level Biology (1400) consists of 5 units. Units 1 and 2 form the AS qualification, while Units 3, 4 and 5 form the A2. Unlike most other exam boards, WJEC includes a practical examination (Unit 5) as a separate assessed component.
