Hello,
According to 2018 cutoffs, it seems pretty difficult to get a seat in an IIT at your SC preparatory rank of 911. Please note that this prediction is completely based on 2018 cutoffs. Cutoffs can vary from year to year based on factors like number of students appearing for the examination, number of seats available, difficulty level of the paper etc.
I hope it helps. For any further queries, ask me in the comments.
All the best!!!
