You score good marks.First, Congratulations!

As there is only few seats of IITs available with uceed examination.Only 52 seats are available including all three IITs under general quota,26seats under OBC and 21 under SC-ST.previous year cuttoff was around 100 marks for general,90 for OBC and 50 for SC-ST.Cuttoff remains nearly same.With general category you won't get any seat in IITs,From OBC there is very less chance and from SC-ST you may get IITs.

For assurance wait till rank and cuttoff declared.

GOOD LUCK!
