Or not ?

In the context of IGNOU (Indira Gandhi National Open University) examinations, "abc id" seems to be a term specific to IGNOU's registration or enrollment system. Without knowing the exact details of what "abc id" refers to, it's challenging to provide a precise answer.

However, typically in educational institutions like IGNOU, students are required to have a unique identification number or code to facilitate various administrative processes, including examination registration. This ID may be assigned during the enrollment process or registration for courses.

To confirm whether the "abc id" is mandatory before filling the examination form, you should refer to the official guidelines provided by IGNOU. These guidelines are often available on their website or communicated to students through official correspondence. Additionally, you can contact IGNOU's student support services or examination cell for clarification on this matter.
