Hello Aspirent
There are lots of courses after 12th for you
If you have interest in engineering then you can go for that.
If you are good in theory then you can do BSC , BCOM ,BA .
you can also do BBA if you have interest in management.
But according to your goal you have to choose courses . First decide your goal.
Best of Luck
Thanks
