Engineering

Sorry with the above result you cann't get into CSE or ECE branch in sastra.

The expected JEE Main AIR of your son is about 127297. Please write about home state and category you belongs for better response. However keeping the last year of trends in consideration, NITs and CFTIs are difficult to get through other state quota if belongs to general category. So please seek the admission in state engineering colleges where you belongs.

Getting a CSE seat is impossible for your mark. You can try for aerospace. In the counselling they will show you which seats left on the time of your counselling based on the rank given by them. So try upto 3rd counselling maybe you can get aerospace.

It's highly impossible to get a seat of CSE in Thanjavur branch, based on your score. If you are very particular in that you have one opportunity join in any branch you got in the counselling then in the first year get CGPA above 9 you can avail your CSE seat from your 2 and onwards.

Its difficult to get SSN College of Engineering. The major admission in SSN are based on merit of qualifying exam (12th marks). Total seats 65% are filled up through single window counselling. The seats offered by SSN are filled up within the first few days of counselling with significant high cut-off marks. The remaining 35% seats of the management quota are also offered through merit. 25 seats are earmarked for students who excel in both their academics and sports and 25 for toppers of Government rural schools of Tamil Nadu.

Dear Sai Krishna, Please reframe your question with more details
