These are A* quality notes that I wrote during my A Levels to help me revise
for A Level Edexcel A SNAB Biology. Notes and resources for this exam
board are very limited so I hope these notes help students that are
struggling to find resources online. I wrote these using my class notes, the
Edexcel SNAB textbook, mark schemes and other online resources such as
savemyexams. At the end of the document, I have written some common
exam questions that I came across during my revision along with their mark
scheme points so you can see which points are important to revise. Once
you have read through topics, I’d highly recommend doing exam questions
and trying to finish the specification as soon as possible so you can do as
much exam prep as possible. I hope these notes are useful for you as they
were for me and I wish you luck in your studies!
