Colleges in Jharkhand

Yes, commerce student can apply and get admission for BCA.
Good luck.

Good luck.

You have a chance to get in, but do good in XAT entrance and GDPI. So start preparing for XAT, self practice and
do take mock tests frequently. Good luck!

See placement depends on various factors. Other thing is that in NIT Jamshedpur, average package of CSE branch is below 5 Lacs. So I don't think initially you can expect that much. May be after few years of experience you can expect that much amount in metallurgy. It also depends on how much skills you will acquire.

Sorry, that's too less to get in Xavier's without any quota.

Expected cutoff will be 85% in CBSE.
Good luck.
