Braving the heat, thousands of students queued up at the 18 colleges where the forms were being sold and submitted.
Traffic jams were reported at DU's North campus as eager students rushed to get their forms on the first day itself.
"42,860 forms were sold on the first day today. Out of which, 35,208 forms were of General and OBC category and 7,608 of SC/ST and Physically Disabled. Last year, the figure stood at approximately 30,000. The number of forms received manually at counters today was 3,724," Dean of Students' Welfare J M Khurana said.
Meanwhile, a section of students complained that the website denied access once they clicked on the online registration link.
