Hello Neha ,

There is no nation-wide recognized B.Sc Life Science Entrance Exam , it depends on the individual colleges and states. Depending on the university you apply to , they will either give admission based on the board marks and release cutoffs or they will have an objective entrance examination based on 11th and 12th syllabus. Please check the official websites of the universities you want to apply to and fill out the forms accordingly.

Hope this answer helps you!
