Dear Hirak,
If you are not interested for going to Master's (through it is recommended), you can still make your career in various other fields depending upon what the skill set you have. After B.Sc. Hons, you can go for civil service exams like UPSE or any other defence organisation's exam. Or you can apply for Data Analyst jobs if you really having some good programming skills along with statistical analysis.
Hope this helps.

You may also take admission from several joint entrances like WBJEE and AIEEE as certain colleges give admission in biotechnology after seeing these ranks.
