Hello, hope you are doing well!

The admission notice for 3rd year is not available on the website of School of Open Learning, Delhi University. The examinations of final semester/year are still on-going, the admissions for UG/PG courses are also going on and even entrance tests are on-going. So, maybe this is the reason the University is taking time to start with the 3rd year admissions of previous year batches. But you can still use the Student Login portal and get the necessary details and notices if any. Here is the link of the official website's student portal of SOL, DU:
