Hello Navya,

As Delhi University has their own material for students studying from School of Open Learning, you have to get the material from SOL center.

Unlike other books that can be brough from any stationery shop that deals in selling universirt books, University of Delhi has their own prints of study material for SOL students, so you will only be able to get the printed copies from the center only.

Hope it resolves your query.

Thank you!
