Hello Varun,
For admission into any government colleges, you need to write any entrance and score well in that, however regarding donation, no government colleges offer admission via management quota.

Computer science engineering (CSE) is one of the popular courses among engineering aspirants which focuses on the basic elements of computer programming and networking. Students pursuing computer science courses will gain knowledge of design, implementation and management of information system of both hardware and software. Going by the name, CSE course deals primarily with the theory of computation and design of computational systems. The course is offered across the globe in technical institutions at undergraduate as well as postgraduate levels awarding B.Tech and M.tech degrees, respectively.

If you have good stuff in any of the core streams then you can get a good placement. In addition to that, you should improve your communication skills along with the problem-solving skills.

In the view of short-run career, you can choose CSE, but for the long run, you can choose IT or ECE as software boom has lost its significance. Whatever stream you take, gain more practical knowledge than theory.

Brother, Diploma in computer science is a bad idea if you have to pursue B.Tech after Diploma. Go directly for B.Tech after HSC, it needs a good knowledge of physics and maths for which HSC is good.
