Most IGNOU students associate IGNOU Assignment submission with IGNOU Term End Examinations. They are not, however.
Aside from one connection: to appear in the respective subject's TEE, one must first submit an assignment; there are NO other connections.
1) IGNOU Assignments and IGNOU Examination Form are not in any way related:
That is, you can choose to submit IGNOU assignments for all subjects while not appearing in the TEEs for any of them. However, because registration for a paper is only valid for two years or four semesters, it is important to continue passing the TEEs. Otherwise, one must re-register for the paper, which is still incomplete (Not passed).
2) IGNOU Assignments that have been submitted and completed (passed or cleared) are valid for the duration of the IGNOU program:
This also applies to the Maximum Duration to Complete the Program. For example, IGNOU MBA takes 8 years. Thus, if a student fails a paper or re-registers for a paper, he or she only needs to reappear in the TEE (if he has already passed the Assignment). As a result, there is no need to resubmit the assignment for the aforementioned paper.
3) Regardless of when you plan to appear in TEE, you must submit only the most recent IGNOU Assignments:
You cannot submit a previous assignment that you wrote but did not submit at the time.
Regardless of whether you intend to take the upcoming TEE or not, it is always advisable to submit completed assignments to the Study Centre or Regional Centre.
4) The Late Fee is not for Late Assignment Submission: There is no fee to submit the IGNOU Assignments.
5) Assignments that have been submitted and passed (Complete Status) are valid for the entire IGNOU Programme, but one must pass a paper within two years of registration: If a student fails to complete or pass a paper within two years or four semesters, he must re-register. This doubles the cost of the paper. Aside from the financial burden, there are no other consequences to re-registration.
