What does everyone think are the hardest parts of Unit 2 (Additional Science) Biology? I want to go over the hardest things. For instance one thing I find difficult is phenotypes and genotypes. What else is there?

I've already done my exams but I was in another post a few hours back and people seem to be struggling with things such as cell division and inheritance. I remember I found speciation quite hard too, some of the questions I got on it were ridiculous.

i get what you mean! you always have to say like "this factor is no limiting" or "another factor is limiting" for the last mark and I usually forget
