According to my knowledge for MBA in any IIMS, you need to give CAT exam there is no IIMs who except GMAT score.

For admission in MBA, you can have Bachelor's degree.

Chances are less WITH this percentile. Score around 85-90 is good enough to get this college.

80 percentile is not enough to get a seat in IISC. Generally CAT cut off for MBA-IISC is around 95-96 percentile.

You can give CAT when you are in final year and after completing graduation. CAT score is valid for 1 year so you can give a try in final year. As you are graduating in 2020, you can appear for this year's CAT.

It is very less chances to get admission in MAH CET.

Your percentage is not seen in the interview, because interview round is an individual assessment. But, your overall score gets affected. If the interviewer knows your score it may psychologically effect his questions and judgement.
