What other GCSE Biology students say
Early feedback from people using the site to prepare for their exam.
“Being able to switch to Foundation and just drill cell biology, then sit a full Paper 1 mock, has made my revision much more focused.”
“The practical questions feel closer to the real paper than generic quizzes. I use the progress screen to see which Paper 1 topics I keep getting wrong.”
“Photosynthesis graphs used to blur together for me. The topic tests and explanations after each answer are what make it useful — not just a score.”
