Yes there is a good scope for BCA and MCA. It also depends from which university you are interested to do.
You should prefer regular studies than correspondence.

For graduates, job opportunities exists in Government as well as Private sector. Also, self employment options are available. After BCA., which is an Undergraduate course, graduates may take up Government jobs that require a Graduation Degree (for example- Armed Forces, Nationalized Banks, PSUs etc).

Good Luck!
