Hello,

For admission to MCA you must have completed your BCA or equivalent.

Some Colleges offer merit based admission and some offer through entrance test.

You must have atleast 60% marks to take entrance test.

As you are doing MEC then you have various options available in every field.

You should have to appear in engineering entrance examinations like JEE Main, EAMCET, etc., to get admission for pursuing B.courseans you are not eligible as you don't have PCM in 12th.

But you can do BCA, BBA etc.

Hopefully this helps!!
