Yes, your son can get a seat. But getting a seat in high demand courses like CSE and mechanical engineering is difficult.
Best of luck.

Unfortunately, no. The demand for CSE is higher and it requires at least 98.5% marks or above 150 marks in JEE. Try in other universities.
Good luck.

You can apply through another state quota. For that, you need to have a great score of more than 90 % to secure admission at MIT.

Write any of the tests such as CAT /MAT /ATMA and send your scores to the college. If your scores are valid, you will be called for group discussion, and then a personal interview is done. If you have done well in all these rounds, you are selected.

If you are really interested in a better future and placements, then Instead of Hyderabad Try for SIMC Pune and Bengaluru. They provide excellent Placements with decent ROI. Best regards.
