Politics or Biology?Watch
benefits, pro's cons, etc
I done Biology AQA, so I might be able to help out a bit on that one.
Throughout different exam boards, you learn quite similar content (to my knowledge)
We leant about:
Cell organelles, prokaryotes and eukaryotes
General info about diseases
Lung structure & diseases (most interesting)
Heart structure & diseases (most interesting as well)
Immunology (second most interesting)
Bacteria (vertical & horizontal gene transmission amongst a few other tids and bits)
Plants (cell differentiation, tissues, organs, organ systems, water transport (very interesting))
Haemoglobin (interesting but not as much)
Classification (the topic I hate)
All the ones I've bolded, are very interesting. I haven't included every bit.
Like just about every topic is interesting (apart from classification, which is tedious) but it is a lot of work, so if you take it, you have to start making good notes early.
It's a constant stream of new topics.
