Hello Radhika, 

First of all congratulation for performing well in your exams. With the best 4 subjects score of 94.75 you will not get BSC computer science in saint stephen's as the last year cutoff for GENERAL was 96.66. If you belong to sone category like SC/ST/OBC, then you will get a seat in BSC computer science at saint stephen's. Otherwise look for other streams.

All the best.
