Hey, I'm not sure if anyones still on this topic...but i might as well answer..
Heaps of my friends did biologys 3/4 last year
and with Exam 1 A and Exam 2 A and SAC A+ (around 22/25 average) they got 39 Study score
whilst another friend of mine for 38 with A A A (19/25 sac average) but i'm guessing his exam mark pushed his sac mark up.
Also another friend got Ex1: B Ex2: A SAC: A and got 36 so i'm guessing the A on exams for you to get 37-39 is low-medium and high A will get you around 39-41 with another high A.
So you should expect anything from 37-41

NOW someone HELP ME PLEASE haha...
I got A+ Mid Year A+ Sac average and i'm pretty sure A+ end of year..
Mid year A+ was 67/75 and my SAC average is 24.5/25 haha...so pretty much 25/25
If i get...67/75 again on end of year..what do you guys reckon i could get??
