Most universities require English professors to have, at the minimum, a Masters degree in literature. With a Masters, you can teach students pursuing an associate or Bachelors degree, but you will need a Ph.D. in literature to teach graduate level students. If you hope to enter a career as a professor of English literature, knowing the general courses you need will help guide your studies.

Hello Prerana,
It's very heartening to see that even in 10th class you have a dream in your eyes. It's actually very simple. After 12th, you should seek admission in BA English. Then PG in English. Clear SET or NET. This will get you job. Then register for PhD.

I think Mahatma Gandhi College of Education will be the best college for it.Shiv Sharda Nursery Teachers Training College can also be a good option to consider.
