Is there any possibility to extend the date of assignment submission July 2023 session ??

As an AI, I don't have real-time information on IGNOU's policies or decisions. However, IGNOU may extend assignment submission deadlines in certain circumstances, such as unforeseen events or emergencies. 

If you're unable to submit your assignments by the original deadline, it's advisable to reach out to your regional center or course coordinator to inquire about any possible extensions. They will be able to provide you with the most accurate and up-to-date information regarding assignment submission deadlines and any potential extensions.

Additionally, you can keep an eye on IGNOU's official website or announcements from IGNOU authorities for any updates regarding assignment submission deadlines for the July 2023 session.
