CAT

Give some regional entrance exam and you will definitely score 50+ percentile in it. Take admission in the relevant MBA college. Don't worry about CAT.

Dear Rahul. The best coaching can only be decided by you only. However from our preference, the best institute ( in terms if studemt output and final selection) you can join is;
#1) TIME
#2) Edushastra
#3) Alchemist. These are some examples of best institute. But choose wisely. It would be great if you are able to make contact with the current students. Hope this helps. Good Luck.

You can get admission in a private college but to get admissions in a government and a reputed college, you have to clear exam. Below mentioned are the best colleges:
1. Narayana B-school.
2. United World B-school. You have to visit the campus and get the information that will they take direct admission or not.
