hi,

After completing bachelors or B.Sc in chemistry course YOU may go for higher studies like M.Sc in chemistry, M.Sc in biotechnology, MBA in agribusiness management etc. ALso after after passing bachelors course you may work as a lab assistant, may apply for government exams like ssc cgl, bank po ,graduation level post in railway and other state and central government job etc.

however if you want to stick in your discipline I suggest you to after completing bachelors , appear in iit jam exam, after msc from iits there is huge opportunity in industry and research work.
