I have completed my M.Com from IGNOU in 2016. Overall experience was good, but I am highlighting the main qualities here.
Merits: -
Easy Exams : Normally the questions asked are of repetitive nature and easy to answer.
Assignments : In IGNOU you got weightage of 25% marks from assignments. So it become very easy to qualify the exam.
Exam Centre : Normally exam centres are nearby you house unlike SOL, where you have to go atleast 30km away from your house.
Assistance : One of the best thing I found was that they reply your mails and picks up your calls and respond to you very nicely.
Programs : They have also got wide varities of programs, rarely found anywhere else in Govt. Institution.
