I’ve struggled so much with feeling overwhelmed…
…with biology revision, and I don’t know where to start. But your website is just what I need! It tells me all the information I need, and the knowledge I need to then build on, and it’s written in a way that soaks straight up into my brain! For some reason I remember everything you have written! Thank you so much πŸ™‚

Frequently Asked Questions

What is an exam board and specification?
An exam board is the party responsible for devising the subject specification and exams e.g. AQA or WJEC. The specification is a document that outlines the bits and bobs e.g. modules, skills and definitions required to prepare for the exams.
Does the content cover everything in the specification?
Yes, it covers every single sentence of content.
Is The A Level Biologist – Your Hub all I need for my exams?
It’s unlikely that you can be confident in exams without using different media such as notes, diagrams, past exam questions, your own notes and drawings, etc. so if you can have, not necessarily more resources, but the right resources for you, which are likely to be multiple, then the better it will be.
Can I use The A Level Biologist – Your Hub content for Edexcel A or B Biology, or a different specification?
Some specs by the same exam board e.g. Edexcel A and Edexcel B Biology are very similar. The actual content per topic or module is the same (knowledge is universal), but the name of topics or their order may be different. In this case you can still use the content, but would have to double check your spec.
