Hello,

this program starts from 2nd year of Course. In 1st year you don't have any major or minor.

If you have taken CSE then you can take major which will has course from your branch only. If you take Minor then you have to select from which branch you want to take minor. You can choose one from the both. You can't take both. Better to take Major it will be good for your career or if you want to take minor take from ECE branch.
