Is it possible to get a 50 in methods, if you're rank 1 with 93% average but you still destroy the exams? Does cohort strength, size and your own average even matter if you are rank 1?
Cheers.
The thing that you should really be worrying about is ending up rank 1. If you're rank 2 and you're worried about rank 1 bombing, it means that R1 has been inconsistent throughout the year and you really should be beating him (i'm talking about small cohorts of size <50, because top cohorts you could be ranked 10-15 and still be okay).
Mind, that for them to actually affect your score, rank 1,3-10 have to all bomb because if rank 3 does better than 1, you'll take 3's scaled sac equivalent. Chances of that happening? virtually 0.
Regardless, if you full mark the exam, for you to not get 50, you'd have to get a low A+/high A SAC scaling or lower. Probably not going to happen.
Tl;dr if you full mark the exam as rank 2, you'll get 50 99% of the time.
