MCA

No, it is not compulsory to have MCA after BCA for a job.
But if you do MCA, you will get high salary package in the private sector.
All the best.

BITS, Pilani does not offer MCA.

Of course! You can do regular MCA after having a BCA through distance learning. Not only in Mumbai or Navi Mumbai, but in all over India, you could get admission in MCA. All the best for your next step.

You can either go for normal entry (3 years) MCA or for lateral entry (2 years) MCA. Both are good if you had done BCA. Lateral entry MCA from any good institution saves your time.

If you had Mathematics as one of your subjects in B.Sc, then you are eligible to pursue MCA.

Hi Anjalee,
As the admission criteria are different in every college, you will have to inquire in each college that you are interested in. There are some colleges that would allow admission to commerce students as maths is the only mandatory subject that one should have in 10+2 and graduation in order to qualify for MCA.

You should not go with the thought that whether the institute is private or government. You should, in fact, focus on whether the institute is good or not. I would recommend B.Tech for you because as per industry norms B.Tech is equivalent to MCA and for MCA you would invest 2 more extra years plus the fee.
