[jalamoushi]

starting to stress out from now!! when i should know all of unit 3 by and how many practise exams should i do? and when should i start the practice exams?

The Biology tips thread suggested revision starting when you start Immunity or something. The minimum recommended practice exam count for each UNIT is 15 per subject.

There is no absolute answer for this. I knew "all of Unit 3" so to speak in the holidays. I didn't start practice exams until about a week before the exam for U3, but did 3/4 a day during that week. I don't recommend this, I was so sick of bio by the time the exam came. I suggest doing one a day starting about a month before the exam, doing 2 on saturday and 2 on sunday. That's what I did for U4 and that worked much smoother for me.

And you don't have to know 100% of the unit before you start the practice exams, you'll find that if you're doing exam questions while learning immunity in class will be beneficial.
