Colleges in Varanasi

BHU is a good college to study judiciary.

No, I think Jaipuria Institute of Management - Lucknow is best for you.

1. Faculty of Science - Banaras Hindu University
2. Rajarshi School of Management & Technology
3. Microtek College of Management & Technology
4. Institute of Computer Science & Technology
These are the best colleges for MCA.

Would suggest option 3 with a specialisation of your choice .

It depends up on your interest.

Ceramic Engineering is a specialised stream, placement opportunities exist only in the ceramic and concerned segments in industry. CS is more like a generalised course.
