B.Tech Computer Science and Engineering

Yes, surely, a successful drop can change year life but for this, you need to do lot of hard work.
For the complete 1 year, you have to sacrifice with each and every thing and should concentrate only on your studies. So, if you are ready to sacrifice and study well. You can take a drop.
Hope this helps.
All the very best.

B.Tech (animation and game design or cyber security and networking) would be the best.

Yes, for sure.
You don't even need to opt for dual degree course, you can get CSE in non-integrated course too, I guess.

It is approx 2.2 lakh rupees per annum without hostel charges.
