After BCA you can take confirmation in the MCA course. The length of the MCA course is long-term. MCA is a long-term post-graduate course. you can apply for the MCA selection test if you have Maths in 12th. If you have done your BCA, doubtlessly you can seek after MCA as a standard up-and-comer. Yet, you should have a valid justification for the whole year. For your situation, it is 10 years which is quite a while. I would recommend you to have a go at upgrading your abilities instead of simply getting degrees.
