Hi Aditi, 

Chemistry is a subject with many opportunities. While a B.Sc alone may not be sufficient to land you into a decent job, there are more options after you pursue M.Sc. You can go for work in research companies, private & public pharmaceutical companies and chemical industries which give you a handsome salary too. Otherwise, there is also the option of taking up a teaching career- in schools or colleges as lecturers.

There is also option to change your field in case you do not find interest. You can prepare for govt exams like CSE, CGL etc. Or you can go for courses like MBA or MSW. The options are immense, you just need to find what you're passionate about.

All the best!
