Hi there,

If you are sure enough that you will do MBA in future then for better rank and better knowledge try to study right from the first year of your B.com. Start slowly but learn and prepare well. After that from second gear prepare the topics well but make sure don't neglect your b.com studies. Then in the third year solve the previous year questions, precise the concepts and also prepare for the interviews( for additional learning). If you start from the final year, then you might get tensed because the course remained for the preparation and also for your B.com.

Give lots of mock tests and target the colleges you want for further education. Don't lose hope in the mid.

Prepare well. You will succeed.

Good luck:)
