I was on AQA and I hated biology up until around the exam period.. I didn't even hate the actual subject, I just hated the work load and the mounts of revision that needed to be done!
In the end, I covered everything and I can say that it is very interesting - learning about the body and the way we function. What wasn't as fun was the EMPA/ISAs ie. the experiment work, which was repetitive and boring.
I recommend it, but revise as you go along with it otherwise it'll be a hell of a lot of stress.
