Resonance...

No, Kota's Resonance is the best for IIT-JEE preparation.

Resonance is best for preparation for IIT JEE because they have best faculty rather than FIITJEE and Eduserv.

Allen is best for droppers because they provide you best faculty rather then vibrant and resonance.

Yes, you're eligible to get direct admission in Resonance, Kota.

Resonance Institute is not good for PMT, but it is a nice option for IIT. For PMT, Sarvottam Career Institute is the best option because they have the best faculty members in India for medical exams.

Resonance doesn't have any official hostel, but they have management that provides you the best hostel near Resonance Coaching.

Actually, FIITJEE is better than Resonance for IIT-JEE Mains+Advanced coaching. FIITJEE is good in terms of practice papers, daily tests, doubts clarification, detail explanation, grand tests, etc.

When I was in 12th, as I remember fee is about 98K (without any discount) for Resonance IIT preparation. If you're a dropper, you may get some percentage reduction in your fees if you've scored well in 12th boards exam. You can call in Resonance and ask for various types of fees reduction they provide and the criteria for each.

I hope this will help you.

Both are not sufficient or good enough if you are average student try opting for regular coaching, if you are among the topper you can do with this but still if you join some coaching it would really help you out in a better way.

JEE ranks can increase or decrease based on cut-offs. So, I suggest you to prepare well and try to score 180+ to get a decent college.
