Colleges in Gujarat

Hi,
As you know, Mithibai College is one of the reputed colleges in India and good things don't come cheap.
The cut-off for Gujarati minority is 79% marks and above.

Hello,
You can opt for any of the following two colleges:
1) Maharaja Sayajirao University of Baroda (MSU), Baroda
2) Rai University (RU), Ahmedabad

You have a decent profile and especially you have a great chance at C & L as they put relatively less weightage on your graduation score.

Depends on your year's admission criteria (check the past statistics, a quick google search will throw up the result). But, I believe you should focus on CAT and think about this once you have crossed that hurdle. All the best.

St. Kabir is the best institute for professional studies.
They give perfect knowledge and always do creative event for expanding our skills. For better future, go with SKIPS.

IIM's I would say aren't the end of the world and you can very well reach similar or greater heights in your career despite the IIM tag. You can look at other Indian MBA B - Schools or Foreign B-Schools, that don't give as much weightage to 10th and 12th percentage like ISB.
Also, I would say it is important that you introspect a bit about your career and look for ways to progress where your past profile would not be a hurdle.

There is no minimum score as such (B has >80% criteria, might have changed so do check)
Put in your best effort for CAT, all this comes later, and you anyway can't change your scores.

Yes, but you need to perform well in GD-PI too.

IIM-Bangalore has some strict percentage criteria for boards (80% above in 10th and 12th, if I am not wrong). So, B might be off the books, but you still seem to have a decent chance at C with a high percentile. I don't want to be blunt, but you will really need to nail CAT hard. Otherwise, try looking at ISB, etc. wherein the admission isn't so marks based.
Good luck.
