Harsh Pande's Theorem of Periodic rise in Marks a.k.a. The 5 minute Theorem

Statement :

All normal students [by normal I mean, those who aren't the geeks or the absolute dumb-asses of this world], secure maximum marks in the last 5 minutes, in comparison to any period of 5 minutes during a 3 hour Exam.

Alternate statement:

The rate of increase of marks increases exponentially during the last 5 minute period of an exam given by a normal student [as defined above], as compared to any segment of 5 minutes, during the course of the entire 3 hour paper.

Corollary:

1. Writing Speed is the highest during the last 5 minutes of exams

2. Invigilators are most distracted during the last 5 minutes

3. Student info exchange is least detected and at it's highest frequency in the last 5 minutes.

Explanation:

All students strive the hardest to secure marks during the last 5 minutes of their exam. They throw caution to the winds and start looking everywhere for the nearest student who knows the answer they don't. Invigilators also, all of a sudden start panicking and moving all over the hall, giving students a better chance at increasing each others knowledge.

Occasionally, our brain also miraculously remembers answers under the "last 5 minutes" pressure. I repeat, this happens occasionally. Even a hint at what the answer could be, maybe a word or two are enough to allow the student to write an entire paragraph on those two new words. These few lines somehow end up getting marks as well.

The last 5 minutes are the most important 5 minutes of the exam.

Proof:

Visit any COEP exam hall during the last 5 minutes, you won't need any more evidence.
