IIM Eligibility

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.

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

Yes, joining a good CAT coaching class will be a good decision.

No doubt Career Launcher and TIME has produced good results in recent past for CAT. In my view, TIME and Career Launcher are the best ones to look for.

Yes, you are eligible to do MBA in IIMs. You have to have a good CAT score and at least 2 years work experience.

The short-listing criteria for institutes vary. To receive a call from FMS, percentile is the major factor considered.

According to the eligibility criteria, you are eligible to appear in the entrance exam.
But you will get admission according to your result in CAT.

Hi there. 5 years experience in MNC is brilliant. You must appear for GMAT. The cut off varies but you should bring 90+ percentile to get into Premium Colleges like Oxford, Harvard, etc. Also you have the chance to get into Iims of you get more than 98.5 percentile score in CAT if you fall under General Category. But my suggestion to you will be, if you have 5+ years of work experience then you should surely go for GMAT!
Thank you. If further queries then you can always ask.
