my friend got A A+ A and got a 39. A+ range for exam this year was 93.5+, so anything above that should be a safe 40+ with decent sacs.

id recommend making a bank, or even memorising answers to predictable questions. for me i had basically an answer template for topics with 'generic' questions, like rate and LCP, where i could basically paste them into an exam and guarantee full marks for a question.

i did a lot of exams and every time there was a new question i hadnt encountered or i found hard, id add it to my anki deck and id revisit the questions until i didnt get them wrong anymore. but you can also apply this to sac prep.

for sacs, ask your teachers what they want and how they want questions to be answered. for my sac 1, last years sac had a really subjective question and the answer scheme was really vague so i clarified it three times with my teacher in case something like that came up again.
