IIM

Yes, middle class can think about it. You can take loan, as fees will be around INR. 20, 00,000 for 2 years. Good luck.

CAT/GMAT is accepted in IIMs.

Yes, you can. the last year's cut-off for IIM-A was 80%ile but for IIM-L, it was 90%ile.
Try your luck.
All the best.

Hello,
You can go for FPM course from IIM which is the fellowship programme in management.

Hello,
According to me, Doon Business School cannot be compared with IIMs.

No, work experience is not mandatory to get admission in IIM. Yes, you can take CAT to pursue distance MBA.

As you have just prepared for it, so don't worry, everything is going to be fine.
Good luck.

Hi Akash,
You have a good chance in getting calls from most of the top B schools such as IIMA, IIMB, IIMI, and FMS Delhi. Rest, based on your engineering stream, 10th 12th boards, and percentiles in individual components (VA, QA and DI LR), you can try predicting your colleges. For reference, the following link might come in use-https://www.shiksha.com/mba/resources/iim-call-predictor
Hope this helps.
All the best!

Hello,Though CAT is conducted by the IIMS, but it's score is taken by many other colleges also. Those are called non-IIM member in CAT.

No, you are not eligible for IIM, because of your low marks in class 10th and class 12th.
