You need to prepare for CAT exam from TIME, IMS coaching when you are in the third year. You find difficulties in solving CAT papers of previous years, you need the help of Arun Sharma CAT books , and you must study your papers in graduation.

It is 99.99 percentile.

No you need to get a good score in SNAP. You will not be rejected because of lack of work experience. Symbiosis does accept freshers without work experience

There is no fixed answer to this. However you are seriously disadvantaged in terms of your percentages. To make up for that you will have to score really well in CAT. In my personal experience you will need at least 99.7 - 99.8 percentile overall. However the criteria to compute composite score changes every year and also the scoring depends on the incoming batch. But in general with 99.7-99.8 percentile you should get more than one call from IIMs.
