I don't quite agree, to me I think its not about remembering
(more of the hardcore engine subjects don't rely heavily on memory
work), but more of relative processing capability, precisely how
others process the exam questions poorer. In the end, its not how
better you perform relative to others but more of how worse off you
are compared to others. You can answer almost half of all the
questions wrong and still get a decent B or C or maybe an A.. So
sometimes sitting in a exam where everyone comes out complaining
about it being difficult is better than coming out of one where
everyone comes out of it saying it was easier than expected. Its
all so moderated, that's y now i think students want a greater
transparency in the grading system..
