Hi Usha, 

It will beneficial for her if she goes ahead to pursue a Bachelors in Education [B.Ed]. However, alternatively she can also do a Bachelor in Arts [English Hons.], go for Masters in the same subject, appear for the University Grant Commission National Eligibility Test [UGC-NET] and then try to attain a professorship in colleges and universities. Apart from doing an English Hons, she can chose any other subject of her interest and then move ahead to get a specialisation in that subject.Know more about how to make a career in teaching by reading Careers360 using the link given below:
