How long does the IGNOU take to send a mark sheet and certificate?

According to the Ordinance, Rules, and Regulations, results should be announced within 45 days of the examination date. The Grade Card can be downloaded from the IGNOU website for any purpose. If you require an original Grade Card for the semesters you have completed, you must contact the Registrar's Student Evaluation Division. 

However, once you complete your program, you will automatically receive your grade card and provisional certificate. Only after convocation will you receive your original degree certificate. Convocation is usually held in April of the following year, following the date of the exam that you took.
