MCA

Dear,
MCA is post graduate course and B.Tech in Under graduate course and both are not same.
MCA is more on the application side (coding, applications etc.) B.Tech is a bit comprehensive and covers the engineering aspects of computer (programming; electronics, hardware etc.)
MCA can be done after graduation and B.Tech can be done after 12th Science.
Thank you
Dev

Reputed college will always help you more, as it will help you to get an on campus placement and I would recommend you to go for B.Tech IT from a good college as BCA+MCA will require 2 more years as compared to B.Tech IT.

Dear,
As per your query, you can consider these universities:
Ambedkar University
IP University
Jamia Millia Islamia
Amity University
Gd Goenka
Jamia Hamdard
MDU
All the best.

If you want to do both the degree courses, chose a college which provides integrated degree (you can save 1 year).
Amity-Noida has a good success rate in job placements.

Dear,
Firstly, How you will able to pursue two regular courses with required dedication?
Technically speaking, if you are pursuing courses from two different universities, many a time, it is allowed (mostly based on the institution you choose). So, check during the admission and proceeded accordingly.
Thank you.

Dear,
Other than MCA, there are so many courses one can pursue after BCA.
1. Master Degree in Computer Management (MCM)
2. Master in Business Administration (MBA)
3. Post Graduate Diploma in Management (PGDM)
4. L.L.B, etc.
