Hello shubham.



MCA means Masters in computer applications which is a postgraduate course.

As you per the eligibility criteria for MCA "yes" you are definitely eligible for MCA.



But usually after B.Tech people go for M.Tech.

MCA is equivalent to B.Tech.

Instead go for M.Tech (CSE). You can do M. Tech CSE by cleaning GATE exam in CS.



There are many students with non CS background cleaning GATE exam with a good score with just 1 year full time preparation.



Rest the final decision is only upto you.



Hope this will help you!!

Good luck.
