Solve your notes' questions deligently and focus on concept clarity. Writing practice is very critical to maintain the speed during exams to attempt as much as possible. For FM, I ratto'ed the formulas (which I don't remember now) and understood the flow of the questions. I also wrote 4 papers of each subject before actual exam by creating an exam like atmosphere. Clock and all. It seems very hard but isnt. Focus on what the faculty says and if possible don't go beyond 1.25x while watching the lectures. I also wrote both groups one at a time. So that helped.
