BCA

You can do BCA by distance education even after six years of gap. You may evaluate distance education universities and make your choice.

If you are technically inclined and want to pursue career in technology then MCA is very good career option. However if you want to have management career in IT industry then MBA will be the right option. Among various specializations, MBA IT will be aligned with your BCA qualification. MBA IT will prepare you for Pre-Sales support, Account Management and Business Analysis in IT industry. But you will compete with normal MBA from good colleges for these roles. At the start of career MBA IT is better paid then MCA but in long run both careers are equally good and paying.
