Anyone not in the OP's situation may wish to skip over this as it's a bit long & specific!
Do not waste time going through your study notes at this stage. Practice the homework questions set by your tuition provider and review the comments on your mock scripts for each of your three subjects.
Ensure that your BPT notes are well organised to take into the exam room with you and you know your way around the tax tables.
If you are taking FM and there are certain topics which you find tricky and they aren't on the formula sheets, jot some notes down as soon as you are allowed to write. eg. Forwards: Add Discounts Premiums Subtract, MMH: Forex receipt from customer, take out a forex loan, Call option = right to buy, Put option = right to sell etc.
Clearly state what you are doing at each step of your calculations so the marker understands what you are trying to do and doesn't have to plough through acres of random figures.
Any numbers in BS are rarely worth more than 5-6 marks. Stick them in an appendix, not the main body of your answer. Don't waste more than 5-8 minutes on them. Focus on the narrative & talking about the cause & effect instead.
Time management is absolutely crucial. Allocate the time for each question in proportion to the marks available for each part of the requirement, then write twice as many points for 10 marks as you would for 5 marks. Stop and move on at the end of the time allocated for each requirement, so that you pick up the easy marks for each part of the question.
If you find a particular question hard, everyone else in the exam room will as well. Write something, but don't spend to much time on it. Move onto the next bit.
Do not neglect any of your 3 papers over the weekend. They all have similar pass rates and are equally as difficult so do a little bit for each. Remember, you only have to get 55% to pass each one, so you only have to show that you know a little bit more than you don't know!
