IIM

This fee includes mess fee, tuition fee, hostel accommodation, etc. It is about 20 Lakhs for IIM B, IIM A has raised it this year says the news and IIM C is slightly lower than 20 Lakhs. IIMs have the same fee .for you.irrespective of how well you scored in cat .for the old IIMS it is around 18-20 lakhs.
So CAT is something which gives you eligibility for the final admission.
So basically comes down to money, if you can afford i would say you don't have to worry about CAT. But getting a good score will definitely improve your chances of getting a seat and some reimbursement.

Yes, you will still have to pay the entire fee.

IIM's are the best colleges in the country if you want to pursue MBA after graduation. The process is straightforward - you need to write CAT exam and then appear for interviews to get admission

Yes sure. You can surely appear for these entrance exams. These are the exams held for the post graduation course in the top IIM. You can appear for these exams. Minimum qualification is graduation.
All the best. Thanks.

No, don't go for repeating the exam. You can continue with it, and try to achieve good percentage in your last year of B.Com. And, for getting admission in IIMS, start preparing for CAT right now and score well in the CAT exam. They will definitely get you top B school or IIMS. Also, do some preparation for GD and PI process.

12th standard marks do not matter directly but during PI (personal interview) ,one has to carry the mark-sheet and good result will only have a positive impact on the interview panelists. Although its not a necessity but good marks in 12th board will surely give an edge to the candidate.

Hi, This was the scenario few years back, but now, if you want to get admissions in top colleges /universities you have to take the test and then interview. Some universities are still taking the test and interviews good placements like Lovely Professional University, Christ University, Symbiosis University, etc.

Hi, For admission in MBA, graduation is the minimum qualification, then universities go for percentage, test and interviews.

As 12% is too low and IIM B is typically known for a candidate's profile. So, you have to get higher % in CAT.
