Hello pragya,

The eligibility criteria of NIMCET are-

1. Candidates must have scored atleast 60% or 6.5 cgpa( or 55% and 6.0 cgpa if sc/st).
2. Bsc/Bsc(hons)/BCA/BIT of minimum three years full time with mathematics/statistics/ equivalent subject as one of the subjects.

So you need mathematics or statistics or any equivalent subject you have pursued full time to get admission.

As you have mentioned you studied mathematics only 2 years, unfortunately you are not eligible.

I hope it helps.

Best of luck.
