It's good to hear that you are interested in higher studies. I heard that you had completed your B.Com seven years ago and currently working as a branch manager in a mutual fund company. My suggestion is to pursue MBA with specialization in accounts and finance. But you need to decide if you are interested to pursue in India or in foreign countries.
If you are planning to pursue MBA in foreign countries, you need to appear for GMAT test. There are many institutes which provides training on GRE. But Texas Review in Hyderabad is one of the best institutes for GRE coaching as it provides specialized classroom training with comprehensive study material.
