Hi, I thought I would share tips from my personal experience. BTW I have already passed all the first 9 papers but I wish I realised this a bit sooner than later , then my study approach would have been a lot more effective.
from past 3 years, figure out what could be the knowledge question (.e- advantages of disadvantages); and learn them properly just so soon as you see the question you can answer then without having to think about those. remember each 20 mark question has more than 50% knowledge based question and these have rarely anything to do the scenario.
understand/memorise small/quick formulas. there is always at least 10-15 OTQ marks on the formula questions. Please note - it would never ask you to just plug the number the number in and calculate, there has to be small trick in there ..SO LOOK FOR IT.
and then study the subjective (where there is no math involved) chapter first to understand the topic; you will have easy 10-15 OTQs on those.
then always remember to evaluate on your answer for the big question which is more likely to be derived from point 1. whether you calculation is right or wrong , you will get the marks for correct evaluation regardless.
That's covered about 40-50 marks which can be grabbed quite easily.
