IIT Bombay - Indian Institute of Technology Mumbai Answered Questions

So if you are already doing btech from iitb it is a good option as you get master degree in 1 year and then pursue higher education. On the other hand if you are getting admission to mtech it totally depends on college there are colleges which are better than iit also there are which are not .Also the fees of foreign colleges is way too high than iits so one need a scholarship too. But at the end it comes to level of college.

you didn't get admission on the basis of jee main first of all you to clear jee main after that jee advance you will get admission in iit Bombay on the basis jee adv rankings, generally cutoff of iit b is 124 that means your rank should be in top 124.

SJMSOM does not officially disclose cut off cat percentile for admissions. However, you can visit various forums to get an idea about the cut off.
The cut off for general category varies from 97 to 98 percentile depending upon the applications received each year.

Cut off and rank varies yearly depending upon number of students appearing in the examination, difficulty of exam and the highest marks scored, so to predict minimum rank is not possible, maybe you can check last few years rank and have a rough idea about the same.

Yes JEE is necessary to get admission in IIT. Percent changes each year depending on the toughness of paper but one must have AIR under 1500 to get aerospace in IIT Bombay. In my year i.e 2014 aerospace closed at 1800 AIR and mark required for AIR 1800 was around 210/360 which is 60% but it changes each year depending on Paper.
