Colleges in Bangalore

Hello Devika,
The admissions to any engineering college these days is normally through some or the other entrance exam. I therefore assume that you have given JEE Mains etc. I am attaching a link that will give you all the required information about admission in this college. https://www.shiksha.com/b-tech/course/b-e-in-aeronautical-engineering-sha-shib-college-of-engineering-chikkaballapur-bangalore-232617

With your CMAT score, you need to fill forms of colleges and then you need to clear GD and PI round and then you can get admission.

If you score more than 99 percentile then you can get a call from IIM and if you have a job experience of more than 2 years and you are scoring more than 97 percentile then you can get calls from only New IIMs.

The entrance exam comprises of 5 sections. There are total 120 questions to be solved in 2 hours.
1) English Language, Comprehension Skills, Verbal Reasoning - 30 Questions, 30 Marks
2) General Knowledge, Current Affairs - 25 Questions, 25 Marks
3) Quantitative Aptitude, Numerical Ability, Fundamental Mathematical Operations - 25 Questions, 25 Marks
4) Critical, Analytical and Logical Reasoning - 20 Questions, 20 Marks
5) Data Analysis and Data Interpretation - 20 Questions, 20 Marks.

It is going to be very difficult for you to get an admission in IIM Bangalore, without some good Work Ex and CAT marks, as IIMB gives graduation marks very high weightage in comparison to other colleges. And, after getting in you will actually need work extra hard to justify the lower marks in graduation that you have (but, with hardwork that is possible.)
Anyway, you can also look at IIM C and L which don't give as much emphasis to past acads.
Good luck.

Since you have not mentioned your university, it is quite difficult to say. But, in general, it sure does seem possible. A lot depends on the marks of people around you (as IIM Bangalore grades your marks relative to others and then gives your application some points). Anyway, it does seem possible, just score as high as possible in your CAT.

I will be honest that IIM Bangalore is going to be very difficult for you. But, you can target IIM C, they give very low weightage to graduation marks.

I would suggest you look at the official site of IIM Banagalore for the same. But, in general you need to give GMAT, prepare a SOP and get some recommendations. All this is then followed by an interview.
