Hey,

There are lots of courses that could be studied by a commerce student after 12th.But first you need to be sure of your calling.

You can take up Economics in your graduation if you want to study about "the production,consumption and transfer of wealth".But make sure you are good at Maths as well for you need some mathematics to study Economics.There are various career options after graduation in Economics.

If you are fascinated by Business studies then go for BBA.

You may take up B.Com which is mostly based on accountancy.You may go for CA which can be done during or after your graduation.It prepares you for well settled career.

A commerce student is not compelled to take up courses related to only Commerce field.You may explore other fields as well if you have inclination for the same.You may go for Law just after 12th by cracking CLAT that is Common Law Admission Test.You may go for Mass Communication,Fashion designing or you may pursue Humanities courses as well if you want to.

Hope it helps!
