MCA

PGDCA is a program which can be done if you wish to go for managerial positions in your career. Doing MCA is not necessary if you keep on doing different certification courses to keep yourself abreast with the latest technologies.

You need to qualify the entrance test in order to pursue MCA.

Usually, all institutes offer admission in MCA on the basis of entrance test results. However, you may try and check with some of the private colleges near your location.

I hope it will help you.
Best of luck.

You need to pursue 3 years MCA after completing B.Com. Only BCA students in some universities are given the lateral entry in second or third semester directly.

If you are not from an engineering background, then you must join a good coaching institute. You need to improve your maths. You should have sound decision-making skills.

If you are good in programming then go for MCA otherwise MBA is best, but I personally suggest you for MBA because it has good opportunities than IT field.
