During GCSE's or with life, I've never struggled to understand and take in a lot of information, however we have only done 4 chapter in class and my head is about to explode. The AS book itself is 12 chapter! There's just so much information to take in and I hate how everything links together, which makes it even more confusing when answering exam questions. In only 4 chapters we've learned cells, proteins, carbs, lipids, enzymes,microscopy etc in such detail and I just think how do people get A or A* in Biology, even when you have to remember and understand so much info?
