Unit 3 has it's tough moments too, like succession, whats that about?

I'm enjoying Unit 2 though, it's far more interesting than the others, well just the genetics bit really, not the stuff about obtaining food, and maintaining water balance.

For some strange reason, my school did unit 2 last, I have two teachers, and one taught unit 1 and the other taught unit 3, and they split unit 2. Very wierd, I thought it might be confusing at first, but it doesn't really matter which order you learn things in.
