Especially strange: "If
 you
 already 
know
 the 
answer, 
don't
 just
 blurt 
it 
out!

 They 
will 
suspect 
that
 you
 already 
knew 
the
 answer
 and 
didn't 
tell 
them 
you've 
seen 
the 
question
 before.

 At 
least pretend
 to
 be
 thinking
 though
 the 
problem
before
 you 
give
 the 
answer!"

It is disturbing that a school as the MIT offers such courses. Apparently, you just exchange tuition for a good job afterwards, instead of getting the best education.
