Dear Ashvin, for admission into Undergraduate programme from IGNOU, your daughter needs to apply before the January 15th, 2019.

For any queries regarding admissions and study centers, you can reach out to them at ssc@ignou.ac.in and they do respond. If you are filling in the application form online, please make sure that you download the prospectus for the year 2019-20 and read it for a better understanding of the Undergraduate programme that your daughter wants to join. Hope this helps.
