Hey aspirant!

To be honest, it is very difficult to predict the percentiles at this point of time as their variation with respect to marks differ from year to year due to difference in total no of candidates and the difficulty level of the exam. However, looking at previous year's trends, you can expect a percentile close to 80, maybe in the range 78-82 . As I have already told you these are only predictions and the actual result may be more or even less than this. At this percentile and the corresponding rank, it is very difficult to get the best government colleges, however, you may get many good government and also private colleges like

Jaipuria Institute of Management

Birla Institute of Technology, Mesra

Doon Business School, Dehradun

Indian School of Mines University, Dhanbad

Also, you can use this CMAT pathfinder to predict what best colleges you would get based on your scores
