Is abc id mandatory before filling the examination form ..
Or not ?

Without specific context, it's a bit challenging to understand what "abc id" refers to in this case. However, typically, before filling out an examination form for IGNOU or any other educational institution, you may need to have certain identification details or credentials ready.

For IGNOU exams, you typically need your enrollment number or registration number to fill out the examination form. This number is provided to you when you enroll in a program at IGNOU. It's essential to have this number ready because it uniquely identifies you as a student and helps the institution process your examination form accurately.

If "abc id" refers to some other specific identifier or credential required by your educational institution, it's best to refer to the instructions provided by the institution or the examination form itself. They should clearly outline what information or credentials are mandatory for filling out the form.

If you're unsure about any specific requirements or have questions about filling out the examination form, you can reach out to your educational institution's examination office or administrative department for clarification. They will be able to provide you with the necessary guidance and support.
