B.Tech

For that, try the college predictor link of Shiksha and
you can get private colleges but if you think to have more no. of colleges and universities you can check for JOSAA site and check out the last year opening and closing of CSE ranks and get the approximate overview that which is best suited coll

If you have interest in Engineering and Technology go for B.Tech. If interested in Commerce Field go for B.Com. Choosing between B.Tech and B.Com solely depends on your interest.
Good Luck.

For this you should search and see the placements of the college consistently and bonding with different companies.
Moreover, you should also, if possible, visit the college and ask the current studying students and take the feedback.

CSE is a demanding branch but apart for this you should also belong to a good institute, if you are from NITS or IITs, I think 5 years integrated is more than enough. But if you are very much interested to do more, go for 6 years.
Good luck.

Both the branches are having a good market demand. I would suggest you to go on with your interest and according to me, CSE is having high market demand. If you are a graduate from a good institute.
Good luck.

If this 19k is your general rank, then you will easily get IIIT
but if 19k is your OBC rank, then I am sorry to say but it will not help you to get into IIITs because your rank in OBC category is 19k, so your general rank is somewhere in 1 lakhs.

Yes, you can opt for it but I don’t think you would be getting a top branch in that college but surely you can get biomedical branch or of same type which is less opted by students but if this is required then you can go for it.
