Hi,
If you have done B.Com & interested in technical, then instead of thinking of Engineering you can do MCA. Benefits; -
MCA is of 3 years but Engineering is of 4 years
Also after the completion of MCA you will get more preferable than B.Tech coz MCA is a MASTER Course. Note* it is only possible to do MCA after B.Com if you have Maths in Intermediate
Hope this would help you.
