Hello,

So, as per your question you mentioned your preparatory SC rank as 2313. You have to understand that it means if you choose IIT you will get a chance to stay there and prepare for Exams which if you qualify will then give you admission directly to IIT for B Tech courses. In this course they will prepare you for subjects like Physics, Chemistry and Mathematics then after a year they would take a test to see if you have qualified and showed improvement. In my opinion if you are aiming for IITs only then you could choose this.

Good luck.
