Please check for your eligibility to pursue M.Sc Chemistry from the criteria mentioned at the link provided below:
M.Sc Chemistry: Eligibility:
As a minimum criterion of eligibility, aspiring candidates need to have completed:
Higher and Senior Secondary levels of education (classes X and XII) with a minimum aggregate score of 60% marks. Graduation (B.Sc. with Chemistry as one of the main subjects), with a minimum aggregate score of 50% (45% for SC/ST candidates). Often, candidates are required to qualify as an institute, State or national-level entrance test for admission to M.Sc Chemistry course. Regards.

You need to decide on the college or university where you wish to apply. Fill their form and if your application is shortlisted, you can take admission. You can go for Annamalai University, Madurai Kamaraj University, Kurukshetra University.

KUK University is no longer an A Grade university it used to be. It has been downgraded to either B or C grade since last year. The system on which university works is horrible. You give your exam, then wait 45 months for your result. If you are unlucky and got a backlog, wait another 67 months to reappear. And then wait 5 more months for the result. So basically, it takes 1.5 years to clear the backlog. I will suggest you to search for the alternatives. If none of the options works, then you can surely join it.

For most of the colleges, eligibility/qualification for M.Sc. Chem:
The candidate must have passed B.Sc. with Chemistry as the major subject with a minimum of 50% marks in aggregate.

There's a lot of scope, though most of it goes into research work.
If you are into pure science and you're interested in chemistry, go for it. There are various jobs you can get in private as well as public sector, you just you need to be good at your things. Major jobs opportunities are in research and development sector, food industries chemical testing, being a professor, etc.
