CAT exam coaching duration is 6 to 7months based on the institute. Ideal time for joining coaching is final year (i.e. June to November), so that you can write exam in December. TIME institute is good.

Hello Anil,
B.Tech is all about the technical aspects, MBA teaches a lot about management and administration of business.
For a B.Tech (EEE) student, MBA turns out to be useful if you're planning to start your own business / company. Certain companies also keep it as a mandatory eligibility criteria for promotion or recruitment to senior managerial positions.
Since, you already have a career of over 5+ experience, I would not suggest you to leave your job. Rather, you could opt for correspondence MBA while you continue with your job.
I hope it helps.

You will be eligible to appear for CAT examination in the final year of your graduation degree.

In order to crack CAT, you need to score very high in numerical ability section of CAT examination. If you are weak at mathematics, you may face difficulties therefore, you are advised to work on your numerical and data interpretation abilities by taking external support.

One year is apt for the preparation of CAT exam. You can start accordingly.

For a general category candidate you need to score atleast 95 percentile in CAT exam.

It totally depends on individual's efforts and determination. If one had prepared well, he/she has good chances to score high percentile in CAT.

Below mentioned are the colleges accepting CAT scores in Maharashtra:
1) SP Jain.
2) JBIMS.
3) KJ Somaiya.
4) SIMSREE.
5) NITIE, etc.

Greetings Sharath
The average CTC at the recent placements was around 9 lakhs per annum.
As for your second question, CAT cutoff lies around 80 percentile but a 90percentile would be competitive.
All the best.
Kind Regards
