CAT

If you gets placed through open camps/on-campus placement, then working for 1/2 year before option for MBA is a good option. Although your academic profile is good, you can attempt CAT this year and try to score 95 percentile. Pursuing MBA from any of top 15 B-Schools is worth. So you if you have opportunity to serve in an organisation, then its an advantage. Without work-experience also, it wouldn't be a big issue.

You have good chances to convert but your graduation percentage is on the lower side. Still if you perform well in GD/PI, then you have good chances to convert. As B-Schools give weightage to GD/PI-WAT/PI rounds.

You can check for IMI-Kolkata/Bhubaneshwar, ISME-Bangalore, VIT, BIMM-Pune, Amrita, IIFM, BIMTECH-Noida, SIES, ITM-Mumbai, SCMS-Cochin. You can consider these colleges.

It is better for you to read The Hindu newspaper daily as it is considered to be the best medium for studying current affairs.

Yes, you can appear for CAT exam after completing B.Com.

Dear Samayak Gangwal,
The last year's CAT cutoff for MBA in NIBM was 73 percentile. There is a good possibility to get a seat in NIBM. NIBM, in fact, has got 18 LPA as the highest salary package.
All the best.
