dear student,

Firstly have a strong base of Maths of 6-10th standard and then transcend towards the quantitative question which U get in all types of management book. Though don't do much of easy things which these books offer and take note of time too. Now for English, the same- take any of the verbal ability books in the market; I took Pearson for IPM which was good at English but not that good on overall basis.

Take note that the difficulty level just rose to a high level (relatively) the last year and it'll go on increasing.

Make sure that U do good in English as its very very easy compared to the quant portion. Also do track your +2 subjects for interview and get a good amount of GK and current affair knowledge by reading news. Though any one of them going good will convert your admission if U have a decent AT score.

hope it helps!!
