Spesh sac marks/study scores, correspondence?

[scisci]

Hey guys, I'm doing spescialist maths and I'm curious to see what your SAC marks were and what they corresponded to as a study score. I'm especially interested in seeing what scores people got to get a 30 they score as that is what I'm aiming for .
Also if there's anyone who did spesh without 1/2, were there any resources that helped you? I'm doing spesh without 1/2 via correspondence (I know, crazy) and so far the feedback from my teacher hasn't been too great (8/18 on some questions about vectors), so if y'all could help me out, that'd be awesome thanks!

If you want a 30 you'll need to average Bs and B+ for all your sacs and the exam.
