IIT Kanpur - Indian Institute of Technology

If you are a average student and know your capabilities then you have to work hard, study hard, concentrate and be focus on your studies only and not anything else .
Just go with the concepts of subject of 11th and 12th , practice NCERT as much as you can, Try to solve every question of the book. Go for previous year paper if you want to go for coaching then choose good coaching for the preparation but do not totally depend on it. Do more self study.
You will definitely qualify for 1 attempt in JEE Main.Also if you are of general category then actually you have to study hard.

Both are better but IIT, Bombay gives better placement than IIT, Kanpur. The infrastructure of IIT, Bombay is also better and it is listed in top 10 universities of India.

You cannot get admission in IIT on the basis of JEE Mains, but clearing it is an eligibility criterion for taking JEE Advanced which is the exam for getting into IIT.
For JEE Mains, you need a minimum of 100 marks to stand a chance, but you are still not in the safe zone.
As every year the cut-off revolves around 100.
For Advanced, the max. rank to get IIT-Kanpur or Kharagpur is 30K to 35K but then too you have to compromise with the branch.

After getting a call, the selection process would depend mostly on your GD-PI performance and since you seem to have decent academics in 10th,12th and graduation above 6 so chances could prove favorable for a conversion. So please give emphasis on your GD-PI preparation now.

You need to get rank under 1000 - 1500 to get admission in any of IITs.
