B.A English

I think if there is any worldview critical edition, opt for that or go for the original edition of 1861 book as new edition has many variations and this disturbs the reader a lot.

No, not now. You have a lot of time, after doing Master's degree, you are eligible for the NET exam. So, you have a good amount of time left. But for now, just focus on BA (Hons) English.

You can go through the below mentioned names:
Agra College
Gyan Mahavidyalaya
Shri Lal Singh Degree College
Krishna College of Science & Rural Technology
Siddhant Raj Degree College
Smt. Laxmi Devi Mahila Educational Institute
Dr Bhim Rao Ambedkar University, [DBRAU] Agra

Every college has a different cut-off, but usually English (Hons_ cut-off ends lastly with 85-80% for general category. I have no idea as how much will it go in 2018. The maximum is 98-95% for good colleges like Hindu, Hansraj, and St. Stephen's.

2018 cut-off has still not been declared. But the cut-off usually ends between 91-96% for general category. You may check 2017 cut-off to get some idea.

You may go for Master's degree and then clear UGC NET to become a lecturer or go for B.Ed then you are able to teach till class 8th in a government/ private school as an English subject teacher.

No, I think you are not eligible for BA (Hons) English in DU because the last year cut-off for the course comes near 89-91%.

Yes you may go for hospitality field if you have keen interest in this . you can go for diploma in hospitality management . it's one year course and , eligibility for this one is graduation in any discipline from a recognized university or institute
Hope this helps

You can pursue this course in Delhi University. But mainly it depends on the best 4 subjects in class 12th and if you belong to the general category, you can get admission in out of campus college like as PGDAV, Zakir Husain-Delhi, SSN and many more. If you belong to SC or ST category, you have a chance to get admission in the north campus college such as Hindu College.
