After 12th commerce if you want to go for professional courses which you have no link with commerce, then I would recommend you to go for BCA course or Bachelor of Computer Application. This course enables a student to study about computer programming and data management etc. SO if you wish to go for IT sector then it would be better for your to go for BCA.

Now apart from this you can go for BCOM or BBA course. BBA is a mangement course where as BCOM is a pure course of studying the subject matter of BCOM. This are the most preferred choices a student of Commerce opt for after 12.
