^ This is BS. You don't write your name at all, just your student id number.
Also, this is the reason students in their board exams (+2 / Twelfth-grade
tests) were forbidden from writing their last name in the answer sheets.
Teachers in India openly discriminated against students from other
castes/jatis/varnas by giving them lower marks.
Didn't you notice the past tense? Also, this defensiveness without properly reading what I wrote is part of the problem. This maybe BS today, but it wasn't 25-30 years ago.
I wrote exams 25-30 years ago. The answer script only had the ID number. We did write the name on the first page but it was torn off before it was passed on for grading.
