GL Bajaj admission query

I scored 84% in Class 12, and my JEE Main rank is >15l. Since I won't get a seat through counselling, I'm planning to apply for direct admission to GL Bajaj.

Could anyone please suggest:

• Which branches are likely to be available based on my Class 12 percentage?
• If I want to pursue CSE, is it possible through direct admission? If yes, approximately how much donation or additional amount is usually required?

For context, I'm from Haryana and belong to the OBC category.

Any recent experiences or guidance would be greatly appreciated. Thanks!
