CAT Eligibility

That won't be possible in general category.

You can go for Chandresh Agarwal or Meena Uphadhay books.

You are very much eligible as AMIE course is run by the government of India.

Eligibility is that you should clear 10th, 12th and graduation with minimum 50 percent (45 percent in case of SC/ST).

To appear for CAT, you need to be a graduate. I would suggest you to complete graduation through correspondence (you can do fast tract Graduation in 2 years), or complete BE to appear for CAT.

To take the CAT, it is mandatory to have pursued atleast a three year graduate course and secured 50 percent marks in the graduate course. For SC/ST, the required pass percentage is 45 percent.

Please use Shiksha Call Predictor, it would give you a better idea. Try and score the highest, I don't think you would want to score a 99.1 percentile instead of 99.9 percentile just because it is only as much as you need. I hope you get my point.

The institute MAT cutoff for 2018 admission is composite score of 550. Though there is no cut-off prescribed for CAT/XAT, a good score will be given preference.

CAT 2017 has been done now you have to wait for next year.
Bachelor's degree in any disciple from any recognized university or equivalent qualification. The minimum qualification is: GEN - 50% | SC/ST/PWD - 45% Candidates appearing for final year examination of the Bachelor's degree/equivalent qualification and candidates who have finished their degree prerequisites and are waiting for the results can also apply.

Hi Shashank,
IPE would be a better option. By choosing IPE, you would become a part of top B-schools of India.
For IPE, Cut-off percentile is 60 and more in any one test. I.e CAT/MAT/GMAT/CMAT/ATMA. So, you are eligible to apply. Final admission is based on academic performance, test score and GD/PI performance. Equal weightage will be given to all.
