Hi,

It is never too late to prepare for anything. Though SNAP requires good amount of hardwork for 3-4 months but you can still score well if you are determined to. I recommend you to prepare yourself a good timetable and study early in the morning as mornings are good for learning. Focus on prearing the basic concepts and core learning. Prepare from books such as Arihant Descriptive General English by SP Bakshi, Quantitative Aptitude Quantum CAT for admissions into IIMs and Word Power made easy by Norman Lewis. Always remember if there is will there is a way.

I Hope this helps,

All the best.
