Hey aspirant,                                                                                                                         I hope this information helps you..                                                                                     You do not have to worry for not having Mathematics in your 12th with Commerce stream for getting into banking sector as it does not demands for a particular subject. But to be eligible for the bank jobs you will first have to pursue graduation degree course with any discipline from any university as the minimum educational qualification for banking jobs is as same.

ALL THE BEST FOR YOUR FUTURE.
