Hi Mahesh!

Yes, you can pursue MCA after B.Com (//B.Com) , but it depends on the college in which you are taking admission.Every institute has different eligibility criteria. As you mentioned about NIT Wrangal, so as per its eligibility criteria candidate must have passed three year degree or equivalent degree from a recognized University/Institute with First Class and not less than 60% aggregate marks (of all the years) or equivalent CGPA of 6.5/10.

Also, the admission is based on the score/rank achieved in NIMCET which is NITs MCA entrance test.
