Hi, 

It is difficult to tell the rank on the basis of marks as it depends upon various factors such as candidates appeared for the exam, difficulty level etc. Also, NCHMCT doesn't disclose the marks of the candidates in the result only the AIR is disclosed.

The result will be declared on 18th May and then based on your rank you can assess the college you will get. 

You can also use our college predictor -
