It is possible that you could get a 40, but you'd need a very strong performance on your SACs and end of year exam.
percentage wise, how much do you mean by "strong" for sacs?
The range for A+ in the 2009 exam was 158-180. That means that those who got exams got on the average scores of 2 markers 79 - 100%. If you really want a score >40 though, you'd have to aim at the upper end of those scores.
A+ is actually 87% to 100% (158/180 = 87%), just to clear that up.
And definitely aim at the upper end of this range if you would like a 40 study score.

I have to tend to disagree with you. I have clearly spoken this over with my teacher.
I think like 11-12% of students get a study score of 40+ for each subject. For this exam 9% of the students got an A+ or above.
So even if you get 2 Low A+s, and good SAC marks, you will definately get 40.
Getting 45 and above then entails getting High A+s.
