B Sc is better option for you

Dear Student 

Step 1 You should opt for a stream of your choice (science, commerce or arts) in Class 12th

Step 2 After completing Class 12th, you should opt for the bachelor degree. It is important that you clear graduation with good percentages

Step 3 You should apply for the postgraduate program and score at least 55%, since it is the minimum eligibility to appear for the NET (National Eligibility Test)-the qualifying examination for teaching in a college

Step 4 Either you can sit for the NET exam or can apply for doing research work in your university. M.Phil & PhD degrees are required for doing teaching in a college. A candidate who possess doctoral degree gets an edge over other applicants.

For recruitment as professors in universities or institutions, it is mandatory to clear NET (National Eligibility Test) /SET (State Eligibility Test) examination. Usually, NET is conducted by the UGC (University Grants Commission) twice in a year- June & December every year. Those candidates who have successfully cleared NET are eligible to apply for the lecturer posts in all Indian universities/Institutes/colleges, but the SET qualified candidates will be eligible for appointment of the lecturer post only in universities/colleges, belonging to the state from where they have cleared the SET exam.

Hope this helps 

All the Best !!!
