Hi,
There is nothing like a good rank. It is a relative term. To get admission in this college you should be in top 1500. Rest be assured, you will get a seat in this college.

In Punjab, the following Universities can be good option for you.
1. LPU
2. Chandigarh University
3. CGC Landran
4. IKGPTU
5. GNDU
6. Punjab University
7. CT University
8. Thapar University
Bangalore : The following colleges can be
1. Christ University
2. PES University

Pune : The following colleges can be good option for you.
1. Bharati Vidyapeeth Deemed University
2. MIT-WPU
3. Symbiosis International
4. Dr. D. Y. Patil Vidyapeeth, Pune

Both the colleges will not accept JEE Mains score for admission. VIT accepts only VITEEE test rank and Amritha accepts AEEE test rank. Coming to fee details, it depends on which rank you score and which branch you are going to choose at the time of counselling and the demand of the branch at that time.

What courses? I am unable to comprehend what you imply. Among VIT and Manipal, I would suggest you consider VIT as your first option. VIT has been awarded #1 Private Institute multiple times.
