SBM has a lot more BS in it than FM, even though the tuition tends to focus on FM, so please don't despair if you find the numbers tricky. The question bank answers are unachievable so don't be put off.
Build up your exam files now even though the exams aren't until July. Put in worked examples for all the hedging questions and business valuation models for example, with arrows & notes showing where each number comes from. Do the same with CR.
Take ACS seriously and do all the exercises properly that you are set in class. Write down all your class mates ideas for things like ethics, industry knowledge etc as well. If your college offers MMM as an extra marked case study, please do it. Set up pro formats again for the financial analysis but be prepared for something quirky on the day. No technical knowledge is needed to pass ACS!
Please ask your tutors before you bombard them with extra Qs. We try to help, but can't always do everything, especially in April & May when we're dealing with ACCA, CIMA & prof stage exams. We try to help as much as possible though.
Don't forget that the exams are structured to filter you in the early stages. We consistently only have 1 or 2 who fail Advanced papers and you've done brilliantly to get this far. I know it's daunting being so near the end, but keep looking at how much you've achieved so far and use that to give you confidence. If your tutor starts spouting the same things in class, please don't out me as a MNer!
