There are not all colleges in India which give importance to past academics. So don't worry much in case of SNAP.  There are 15 affiliated institutes of Symbiosis International University across India accepting SNAP scores for the admission to MBA programme.

The candidates are shorlisted based on the cutoff score for further rounds that is GD/PI and WAT. There is not much focus on past academics so you should focus on getting a good percentile and for later selection rounds.

You can check the list of SNAP participating colleges here.

Good Luck.
