Yeah! You have good chances to get your desired course in SSN. Prepare for the aptitude and interview test. Spend 2 hrs daily to perform well in your aptitude test (if you feel completely blank after your 12th exams!). Be confident while attending the interview.

For us, they asked questions from general aptitude, few chemistry and mathematics (11,12 th) and some questions from Indian politics (such as laws and the constitution stuff).

25 questions : +4 for correct answer and - 1 for wrong(total - 100)

Even if you don't get ECE or CSE take any other group, later you can slide from that (if there are vacancies).
