Is it mandatory to submit the assignment before filling up the examination form? After doing the re-registration for the 2nd year

Yes, it is typically mandatory to submit your assignments before filling up the examination form for your courses in IGNOU. 

IGNOU follows a continuous assessment system where assignments play a crucial role in evaluating your understanding of the course material. These assignments contribute towards your final grades and are a prerequisite for appearing in the term-end examinations (TEE).

When you re-register for the second year or subsequent years of your program, you are expected to continue submitting assignments as per the schedule provided by IGNOU. Therefore, it's essential to ensure that you have submitted all your assignments for the courses you are planning to appear for in the term-end examinations.

Before filling up the examination form, make sure to check the assignment submission status for each course. If any assignment is pending, complete and submit it before proceeding with the examination form submission to avoid any complications or delays in your examination process.
