One of my friends had a very bad experience in IGNOU. She applied for CCP which has 6 months of certification but the university allowed 2 years to complete it.
She wanted to complete the course within 6 months so she appeared on all the exams on time. She had to follow up with her professors for project work daily. After she did submit her project, they lost it. After 5-6 months the Delhi branch called to inform her that her project was not good enough. Apart from this episode, she shared more drawbacks she faced:
Out of 8-10 classes only 3 were conducted.
They took 6-7 months to inform her that the project wasn’t good.
She did not receive any books and had to get them personally by visiting the centre 4-5 times
They increased the fees suddenly in the second year
She scored 1st division in CCP but did not get the certificate for the same. So it’s not recommended for you to do PGDCA from IGNOU.
