SOL is a short form for the School of Open Learning at Delhi University. It offers admission in different UG and PG courses offered by the DU colleges. The major difference between DU and SOL is that you don’t have to attend regular college. 

Here are the other differences between DU and SOL. 

• SOL provides admission in correspondence courses and you don’t actually have to attend the classes regularly.
• Whereas in regular colleges of DU, you will have to maintain a certain percentage of attendance in order to take the internal/external exams, and hence you have to attend the colleges on a regular basis.
• SOL is one of the best options for those who couldn’t take admission in any colleges or are dropouts or working people. Also, those who are preparing for the government exams and for a safe side want a professional degree as a backup.
• In SOL, attendance does not matter much and you can easily take the examination which is held once a year without any problem. 
• Finishing a degree can be quite effortless since the classes are usually held on weekends and holidays. 
• SOL also provides study materials to its students. The questions asked on the term-end examination are mostly from the study materials provided by the institute. 

If you are interested in SOL then you can go ahead and take admission in it; if you are working or due to other reasons you are not able to pursue your PG in a regular manner. For this, the SOL assists you with study material as well.

After successfully completing the admission process, you will receive an SMS regarding the study material. It will contain the exact date, place, time, and counter number for the collection of books. You can take the acknowledgment slip directly there and collect the same. You must carry your SOL ID card along with the fee receipt.

SOL also provides courier service and delivers the books to your address but you might need to wait a little longer for that. It is possible that you might not get the complete study material through courier. The best possible option, in this case, will be to visit the main office at SOL.

SOL is a good option only when you are looking for just a degree but it does not carry a great value in the industry. In every sector, while competing for a job, regular students will be given the first preference and then the SOL students will be valued, although the degree will be the same. 

I have even seen some work postings referencing "SOL understudies are not qualified to apply". In the end, regular students are preferred more over SOL students irrespective of the degree.

Yes, a degree from DU SOL is most certainly valuable. But it is recommended to pursue some other specialized course, as an SOL degree might put you in a difficult position while seeking job opportunities.

It is suitable for those who cannot attend classes due to their time invested in some other program. If you are too in such a position then it would be like a cherry on the cake.

You would most definitely be able to secure a job with SOL degree but preparing for other competitive exams, establishing a business, or practicing a professional course would turn out as a huge advantage, giving you an edge over other aspirants.
