Hello Satinder!

DUET is the delhi universitu entrance exam for admission to mostly the PG courses and also some UG courses like BA Humanities, BA Social Science, Mass Media etc.

For b.com there is no entrance test, so you don't need to give DUET for getting admission to BCom courses at DU. The admission to BCom courses at DU occurs through the cutoffs, i.e., marks scored in best four subjects in class 12th from a recognized board.

Hope this will be helpful for you!

Thankyou!
