BumbleBee Exam Time

BumbleBee has no exams to take but it knows exams-time's approaching when:

• Bathrooms remain unused for days at a stretch. Undergrads prefer to dwell in the placebo that time shouldn't be wasted in something as ephemeral as hitting the showers.
• Love-birds are missing from their usual spots in the campus in the evenings. Instead, they're found in the library.
• TAs assume god-like status with worshippers frolicing around lest the TA should utter words of wisdom or leak info about the "important" chapters.
• The photocopier near the library has a thriving business.

BumbleBee studies the alertness level of an undergrad student in the neighbourhood of exam-time.
As expected, the stud's alertness level drops severely once the exam starts. The stud elevates to a state of trans for 3 hours. Words read / hour is way greater during exam-time than during prep time. This is also because during exam-time the stud has to read not only his own paper but the paper of his/her 6-neighbours as well.


BumbleBee stumbles across the undergraduate lab where a TA is checking assignments in person.
TA: You're busted. It's not your code.
Stud: oh.. no no no. It's 100% mine, sir. You can ask me anything.
TA: Um...ok.. tell me what's a linked list?
Stud: Well, Oxford dictionary defines a linked list as......
TA: Get lost
(the student departs)
Stud (to himself): What got him suspicious? Someone must've tipped him.
TA (to himself): Huh.. That code is definitely copied. I showed the same code to my TA last year!
