How to revise.?

Hello everyone , hope everyone's doing good ! I would like to know the order in which I should be revising the subjects for the May 2015 CA final attempt and time that I should allot to each subject.. It would be my golden attempt and I don't want to commit any blunder.. Practical subjects like accounts , costing, SFM and Direct Taxes are my strong zone. Theory subjects are a bit difficult to retain for me.. Most probably I will finish my course by the 1st week of March and approx 55 days would be left.. Help me out ! Thanks in advance :)
