The method that the heads of the Faculty of Mathematics at the Technion
use to torture the first year students.
It's an 'innovative' way to submit calculus homework, without needing anyone to check them. The poor students get about 1-2 sheets of homework a week. They usually concentrate on this hw while neglecting the rest of their courses. Thus causing big gaps of understanding in those courses, not to mention on calculus since those homeworks don't really help, (nobody actually does all of them without cheating anyway).
