CBSE

The next year, the improvement examination is typically held. The improvement exam is open to students who took the board exams the preceding two years. For instance, applicants who passed the 12th board exam in 2021 or 2022 are eligible to take the 2023 12th CBSE improvement exam

Yes, you can get admission, but in private colleges and some of the low grade government colleges too. The eligibility criteria in the qualifying marks (12th class) is 60%. You are eligible.

Yes, you can get admission over there through 15% of NEET quota provided you'll have to score good may be above 560.

Possibilities are quite low to get into CSE IT group of sastra but still you can try for 2nd and 3rd round of counselling But you may able to get into Non IT group of sastra. Considered both for higher possibilities of admission. 

Thank you
