Junior Freshman Science exams tips !?

Provided this hasn't changed since last year, for Biology 1 you have long and short questions. The long questions are divided into 2 sections, with the first covering biochemistry/genetics and the second covering micro/developmental biology. You can just focus on one of each if you want, but make sure you know it well if you're doing that. You'll need knowledge of all aspects of the course for the short questions anyway.

I can't remember much of the Biology 2 MCQ (or most of that module) to be honest. When I got my results I'd done quite well in the continuous assessment so despite only studying for it the night before I got a high II.1. I would advise studying sooner than that though :P

You get a good bit of guidance for the first chemistry paper so I wouldn't worry about that too much. Again my memory of chemistry 2 is shaky because I didn't keep it up this year. I will say that I was worried about failing and did the bare minimum required to pass, hoping to just get 40 and be done with it. I ended up getting somewhere in the 50s, which I know isn't a great result but I was awful at organic chemistry and had missed a few inorganic lectures due to family stuff so if you're in any way better than I was at chemistry you should be fine.

Agree with the above about maths, just do tutorial questions and past exam questions and you should be fine. It may be difficult this year as I think the maths lecturers have changed a bit so the style might be different in exam Qs, but overall the theory should be the same. Best of luck!
