Dear Akshay,

 155 marks in IIT JEE are very decent for this year. As the examination  level of difficulty was about the same as of the previous year, the  cutoff marks as well as opening and closing ranks will remain more or  less the same.
So at 155 marks, you can expect a rank of 150 - 200  in SC category. So there is a very good hope that you'll get an IIT  seat in a reasonably good branch.
Just wait for the results, your  chances are quite fair.
