Hi,

You cannot convert percentile to marks. You can only get your approximate rank from your percentile. You can calculate your marks based on the answer key & your response sheet released online. I would suggest you calculate your marks based on this and then go for cutoffs.

You can use the college predictor, to find the colleges which you can expect based on your percentile.

Good Luck!!
