First of all, are you asking about 2018 CAT? If yes, maximum of the colleges have closed their registration forms and you won't be to apply for most of them. Still, if you are interested to know about it, use the Pathfinder at Careers 360 website. Follow the link: https://bschool.careers360.com/pathfinder/cat
Now coming to the reality part, you won't be getting any "good" college with your percentile. There are some good B-schools in India that are well known for their finance domain. And they do not accept any marks less than 95 percentile. So, even if you are getting a college that would be below average for sure.
Let's come to the GMAT part. You need to score above 710 to get very good colleges. Irrespective of whichever country you want to study, you need to appear for GMAT. Having said that, you can also score above 630 and you would find good colleges. You need to apply to these institutes after getting your GMAT score. You will have the option of choosing up to 5 colleges immediately after you finish your exam and your scores will be sent to them. You need not pay for it because that would be covered in your GMAT registration fees. Apart from that, you have to apply to other colleges for which you need to pay.
Needless to say, it will be a costly affair. If you are ready to invest in it, please go forward. If not, kindly prepare for CAT 2019 and along with that do appear for XAT, IIFT, TISSNET, SNAP, NMAT, CMAT and MAHCET. The colleges accepting the scores of these exams are equally good. Please don't bother yourself with MAT again as most of the good colleges do not accept MAT score.
Hope this helps. All the best!
