This is from my memory bank, so feel free to suggest changes…
- BITS has multiple Profs for each course, so at any point in time during insti hours, chances are, someone is teaching that course you’ve registered for.
- Registration for each course under a particular Prof is based on one’s PR Number. However, one is allowed to register under a Prof and attend another because he is considered to be the best. (Prof JC Pant, for instance, would have close to 300 students attending him for LinAl back in my times, at least in the beginning of the sem. That’s half the frickin’ batch and S39 would resemble a Mumbai local when the class got over.)
Now if each Prof were to take attendance, one would find a funny situation, of students attending class and yet being marked absent, because they would have attended a Prof of their choice and not the Prof they registered under.
