Dear Heeramani, 

In DU, cut off for B.Sc is calculated on the basis of the marks you scored in your 12th in PCM/PCB.  For B.sc in Computer Science, the cutoffs are calculated as the accumulated marks you scored in 12th in mathematics, one language subject and two best elective subjects. Your PCM 92% will be counted as for admission in DU. DU will issue its first cut off list for undergraduate courses on June, 28. The second will be issued on July, 4, the third will be on July, 9, the fourth will be on July, 15, and the fifth will be on July 20. You can check cut-off list by logging on the official website of DU:

So, let's hope you will get a good college to pursue your desired course.
