Hi 

After 12th you have to earn a bachlbache degree in chemistry field and after that you should apply for post graduate degree programme and score at least 55% marks since it is the minimum eligibility for NET exam

It is qualifying exam for teaching in a college.

Or you can apply for M.phil and pH.d degree are required for doing a teaching  in colleges.

Thanks
