Dear Naren,
You can join both the govt and the private sector. The list of both of them are:
Govt:
1. You can get any state psc jobs like BDO, SDO, clerk and CTO but you have to prepare for it but it just needed graduation and you will be a graduate after BSC.
2. You can get any railway job where they need the only graduation as a minimum educational qualification.
3. You can get any central govt jobs and by applying for SSC CHSL, CGL and after clearing them you can be a central govt employee.
4. You can also go for the other govt jobs too because more or less every job has the eligibility criteria of graduation only.
Private:
1. You can start your career as a teacher by applying to any private school and also as a home tutor.
2. You can get a back office job in some office if you have knowledge of computer.
3. You can apply for the ground staff jobs in airports.
4. You can apply for the back office jobs at the bank too if you have their eligibility criteria.
But if you want to work in the core area of your education background I must suggest you study further as that will only help you to land a job in that.
I hope this will solve your query.
Good luck.
