Dear Indranath, it is an achievement of its own if you get a call letter from SCIT. Generally, in the next rounds, they don't ask you groundbreaking questions. They ask you the basic questions for which they expect you have the answers. They only ask you questions so as to see your Interpersonal skills and adaptive skills. What if you don't attend the rounds and feel bad few years from now on? I would suggest you give it a try. There are only 2 possibilities that might happen. You either get a seat or you don't. If you don't get a seat, you at least know that you tried. Never quit before the miracle happens! Good luck!
