CBSE

You need to score very high marks in UG and must have a minimum of 2 years of work experience. You should have cleared CAT with high percentile. Should possess good communication skills and should be able to answer anything in the interview.

No, it's completely impossible to get admission in SD, but you can try somewhere else.
All the best.

Yes, you can get admission for B.Sc in a government college with 70% marks but you will face problems in finding admission in DU north campus as their cut-offs are very high, chances are there to get admission in DU south campus and you can get admission in government universities located outside of Delhi and NCR region.
Good luck.
