I am assuming that you are looking for best colleges for pursuing B.Sc in Rajasthan.

You can consider the following colleges:

1. University of Rajasthan, Jaipur

2. Jaipur National University

3. NIMS University, Jaipur

4. University of Kota

Most of the good universities are situated in cities like Jaipur, Jodhpur, Bikaner, Udaipur. Would urge you to look for admission in such colleges situated in these cities.

Hope this solves your query.
