B.Sc

No, you have to take admission in the first year.

No, no such institution gives admission like this. You can give the backlog papers, but you already have gapped four years. I don't think you will be allowed now.

Hello Sneha,
BVP conducts offline exam for selecting students for it's various exams. For this student must apply online. The admit card is downloadable and is also sent by post. I am attaching a link that will give you all the required information about different aspects of the CET conducted by BVP. https://www.shiksha.com/university/bharati-vidyapeeth/bvp-cet-exam?course=717
Best wishes to you.

To the best of my knowledge, there is no entrance test for B.Sc. In DU. The admission is conducted merit-based as determined by various cutoffs issued by DU.

Your marks is very low. So, there is very less chance to get any of this course. Good luck.
