I haven't started studying so should I give F5 or F7 paper in March orelse I should go for June attempt ?
If you have attempted F2 and F3, you can see whether you have a good command of very basic knowledge required for F5/F7 to help you make the decision.
If you have completed the first three exams then you may take performance management as your first exam in march for which the last date is 8th feb.
No matter which subject you choose, work hard to grasp the concept & you will get through. Complete devotion is required.
