To be honest not really. A lot of people in the cohort will score really highly in the SACs (you know 95+s probably at least 15-20 of you) giving the perception of a good cohort but on the exam they won't do so well. That's why each year only a few get 45+ (3 in 2010, 2 in 2011) and the rest of the high SAC scorers hover around 38-43 thats the harsh reality of it. That's just based on past scores at WSC.
However maybe this year you guys are a lot better? Anything is possible just do your best really
EDIT: To get a 50 she basically needs full marks on both exams and a really high adjusted SAC score (97/100+? or something like that). My brother had 100 SAC and dropped 1 mark in exam 1 full marks exam 2 and got a 50 which was in 2010 so yeah the top end is competitive as hell.
