Yes, there is a good chance that you will get a call for GD/ PI with either of your scores.
Keep a track of the college website after the XAT and CMAT exams results and apply for the process.

For general category cut off is 70 percentile and please do not consider MNNIT as your list for MBA college.

That's fine if you don't have work exp. You can get selected based on your GD,PI and write up performance and your MAT score is also good. Yes, you have the prob. of getting selected because admission result will be based on your performance here at BIMTECH, your graduation marks, co-curriculum activities, achievements.

Yes,you are eligible to apply and can expect a call for PI.
Eligibility criteria can be found at :https://www.amrita.edu/school/business/admissions

You can still try because your selection criteria is not only based on your CAT percentile but also on you 10th 12th and graduation marks and also your GD,PI performance and your work experience if you have any. It also include extra curriculum activities and all these have some weigh-ages. CAT percentile also varies every year and first preference will be given to the pool of candidates meeting the criteria required for admission. For more information you can call on college admission office and if required you can contact me again .
Thank you

The cutoff for 2015 admission was 73 percentile for CAT (2014).

Yes . Candidates with cat scores of 70 were called for GDPI last year . So you have a great chance of being called.

Amit, the SPJIMR admission process is a bit different as they judge your entire profile rather than just marks. So I can't be sure while judging but yeah you may have a chance of a call. All the best!
