Colleges in Rajasthan

BITS is amongst the top colleges in India. According to me, you should go for BITS, Pilani.

Vishwakarma Institute of Technology, Pune (previously known as VIT, Pune) is not a government college. But it is the very first private college in Maharashtra to get an Autonomy.The admissions are merit based. The closing ranks for almost all of the branches are pretty high near about the closing ranks of other renowned Government autonomous colleges. So, not being a government college doesn't make any difference to the genius crowd getting admitted to Vishwakarma Institute of Technology, Pune.

Placement wise, BITS Pilani is the best.

BITS - Pilani does not offer any course for aeronautical engineering.

If you are talking about Rajasthan, then Jaipuria Management Institute in one of the best institute for PGDM.

No, you would not be able to surpass the cutoff (which is minimum of 300 out of 450) if you only prepare for the 12th syllabus. The 11th syllabus is as important as the 12th and carries equal weightage (might vary a little bit). It is advised that you prepare both the 11th as well as 12th syllabus. The questions would be direct and easy. Just try to focus on the important topics. Hope you do well.
Best of luck.

If you will work hard, you will be able to get admission in BITS - Pilani. You can refer to class 11th and 12th NCERT books. You should try to solve logical questions, mathematical reasoning base questions and many more.

There is no centralized counselling for any of the colleges. All these colleges have their own separate admission process.

BITS Pilani is top private university for Engineering education equivalent to legacy IITs and has All India ranking of 6. BIT Ranchi is far behind in ranking in comparison to BITS Pilani.
