Hello Aagam,

Hope you're doing well.

Your academics are quite strong. MBA colleges such as IIMs, FMS, etc , they look for people who have a good academic record, CAT percentile of more that 95, mostly. And, if you have a good hold of communication skills(professional), you'll surely be preffered.

Apart from CAT preparation, During your Bcom, just focus on your studies and try to keep your CGPA decent and good. Try to engage in extra curricular activities. Work on developing your skills. And, if you have working experience, more preference would be given to you. So, you should do a few internships and if possible get some job experience after completing Bcom. You should follow books like RS agarwal and arun sharma for a good hold of quantitative aptitude, logical reasoning, data interpretation, verbal and nonverbal reasoning.

All the best.
