It is not possible to revise the entire syllabus in a day. But u can go through 85% of the course, if u go by proper planning. Divide the entire course to 3 parts:
a) Topics which are expected to come for sure eg in dt u get 1 ques from PGBP always, 1 from ass procedures. likewise in each subject u will find topics which are certain to cum. In law 25% portion is covered by Directors, so go thru each & every word of it.
b) Secondly choose those topics which u have prepared well irrespective of their frequency in the previous years. CA examinations have no set pattern, so may be the topic u have prepared comes in the exam.
and remember one thing, dont put pressure in the mind to revise each & every thing becoz u will end up revising nothing at the end of the day.
Plan according to ur preparation & dont compare with wot others have done or left. Jot down the topics for the last day
