Thinking of leaving my offline degree for dbe, should I?

So yea the thing is I took admission in the bba program at a tier 3 college (amity to be precise), I did not have any expectations that I'll get selected but now that I have been selected, I'm very doubtful about doing 2 bbas together...

So yea I'm thinking about leaving the offline college and focus fully on dbe

But the thing is that, I'll not be having any "offline exposure", So what to do.?

Also, if I do dbe standalone, I'll probably work at my family business as I plan to expand it later and also I'll prepare for CAT
