Hey!

Both IGNOU and DU are well known education centres and offers quality education. But IGNOU has varous centres of education in all over India as well as in foreign contries, so here is a plus point that you can choose the centre as per your convienence whereas DU is only located in Delhi. Also, the Fee of DU is high that IGNOU. IGNOU accepts scores of entrance exams such as IGNOU OPENMAT , NCHMCT JEE  etc to offer admission to candidates in different courses offered by it.

Hope it  helps to clear your delimma.

Thankyou
