My first question would be - why are you even attempting ICET? Is it for MBA? You are well qualified for this. The eligibility for this entrance test is a 3 year degree with Mathematics as a mandatory subject in degree or 10+2. They have not even considered an engineering degree holder anywhere.

Frankly, this is not an exam I would recommend for a B.Tech student. There are better exams if it is MBA and seriously your B.Tech holds more value than MCA. Pls re-consider. This is ideally not a good decision.

If you still need to apply well - you have to enter the main subjects you studied which will be ECE.

Good Luck...
