What happend on your first day at IIIT Allahabad?

My brother attended IIT Allahabad. His first day was normal and hectic with all the admission procedures and formalities. But his first-class experience was quite amusing. Here is how it went. 

One or two days after admission, he is taking the campus tour with our parents. While entering CC - 3 (Computer Center -3), my father casually asked the guard, ‘Where are the classrooms for freshers?’ To this question, the guard replied the classes have started from that day only from 10 A.M.

It was around 10:25 A.M by then and my brother had no idea or any notebook with him. My parents kind of pushed him to attend his first class anyway. He was already 30 mins late. He took a quick peek at the class and according to him, the professor looked lenient. So, he took a chance and tried to sneak in quietly. Nonetheless, the professor saw him and asked, ‘Are you 30 mins late for this class or 30 mins too early for the next one?’ In response, the whole class burst out in laughter. 

Later he got to know the said professor was the HOD of the Mathematics department. Needless to say, it was quite a start for my brother.
