He has already informed that he is a B.Sc (Hons.) in Maths. M.C.A. course cannot be pursued by a candidate unless he has already acquired B.Sc. degree. It is NOT necessary that his B.Sc. degree should be related to Maths only. Candidates with Graduate Degree in any discipline (3 yrs course) with Maths in 10+2 level are also eligible for admission in M.C.A. course.
