What are the chances of converting NMIMS Mumbai at 238 all sectionals clear ?

It depends on the relative score. NMIMS Mumbai usually has a cutoff above 245, though, their batch is already large, so you may convert the college with right preparation.

My NMAT 2024 score - 245 . 9/9/8 is my academic score and 34 months work ex and 1 year gap. Kindly suggest my chances of converting NMIMS Mumbai core MBA.
