Humanities & Social Sciences

It depends on you whether you want to learn by yourself or through some good English classes.

Hi
While you are interested in both these subjects right now, it more depends on what kind of career are you looking for. With B.Sc, you may choose M.Sc later or either go for mba.
With eco you can go for m.a /IES or mba. Education and research both are open for you with these subjects. so make a wise choice as per your skills and personality.

You should study through UG and PG books.

You should go for B.Sc. in computer science.

Fpr Admission in English hons in Delhi university
To get admission in English Honours [B.A. ENGLISH (H)], your percentage in Class 12 exams is considered. Every college releases its own cut off list, till no seat is left vacant.Generally, 10 lists are released.
Your % should be equal to or more than the % in cut off lists.
Good luck

Yes, obviously you can do engineering but it depends upon the cut-off of the colleges.

You read NCERT books through out and make a short note for each topic. You may find reference books like history of Bipin Chandra and many more but read first you NCERT books once.

Jai I suggest you do your regular BA adn then do MBA with specialization in Travel & Tourism.
