There is no difference between the courses followed by SOL at the University of Delhi. However, once the semester system was started in the regular colleges under the University, some differences have been seen. There is nothing to worry about, though. The syllabus of SOL is good.
The courses offered in SOL are year wise whereas the coursework of the regular colleges is semester-wise. SOL is basically for those candidates who are also employed. All the processes are carried out online. It offers courses like M.A., M.Com, B.Com (Hons.), etc.
