I did my undergraduate degree at Wits University in Johannesburg. My Real Analysis course was SO boring. The lecturer basically wrote on the board:
Lemma: ......
Proof: ....
etc.
Theorem: Let epsilon < K, ....
Proof: ....
--QED--
which we all dutifully copied into our notebooks. Very uninspiring.
But when I got to the University of Waterloo for graduate studies, I had a real competitive advantage over my peers for the theory courses I took: I knew what a proof was, and how to do one.
