B.Tech in Bangalore

Yes, Alliance University is a good university for B.Tech in computer science and engineering. there you will be getting a lot of opportunities, exposure and knowledge. The one thing that you have to maintain is your score.

From BMSCE Bangalore, SVUCE Tirupati, and GNDU Amritsar for B.Tech in CSE department, I'll prefer you to opt for the BMSCE Bangalore as this is the best college all in terms of placements, infra and faculty.

Hello,Any student other than those belonging to Karnataka also can pursue their Bachelor of engineering courses in the state of Karnataka. The only restriction is government colleges or government aided colleges. They restrict admissions to students who belong to Karnataka and who had given KCET examination. For privately funded colleges a different examination called COMEDK is conducted and you can get admission to non-aided private Engineering Colleges through this test. There are many Deemed to be universities in Karnataka also which conduct their own examination on an all India basis. Best wishes to you.

Here is the list of top engineering colleges in Bangalore. https://www.shiksha.com/b-tech/ranking/top-engineering-colleges-in-bangalore/44-2-0-278-0.

If you are seeking admission in electrical engineering branch then my suggestion would be VIT. It is one of the most reputed private colleges after BITS-Pilani. It is the best option in every context whether it is the environment, placement, fest, exposure or anything else. It is better than BMS-Bangalore. BMS-Bangalore is also a good option. Now, it's up to you, but first of all, you have to clear its entrance exam.
Good luck.

The applications will be available in the month of April next year.
