Hii Adesh

There are no entrance exams for get admission in B.sc(hons) from DU as of now.

Your admission to B.sc(hons) in Delhi University are based on merit list / your class 12th board percentage .

Improve your board percentage and you'll get through it . For more information regarding admissions to B.sc(hnours) in Delhi university you can visit - https://university.careers360.com/articles/du-bsc-hons-courses

you can apply to other central universities where admissions are on the basis of entrances like JAMIA MILLIA UNIVERSITY , ALIGARH MUSLIM UNIVERSITY, BANARAS HINDU UNIVERSITY and many more

Hope it Helps..

THANKS!!!!
