There are both the options available like you can either go for job or higher studies but as per my view I would suggest you to take admission in PG in your respective field once you are done with your graduation as you can also join non-science master degree courses such as animation, management, journalism, computer technology, etc after the completion of B.Sc degree. Also, below I am mentioning few job profiles where candidates with B.Sc/M.Sc degree can appy -

Scientist, Scientific Assistant, Research analyst, Researcher Biostatistician, Clinical Research Manager etc.

Also, if you want to go for PG then all institutes and colleges have their own admission and eligibility criteria so please tel if there is any particular one in which you have maximum interest.

Good Luck!!!!
