Nokio,
The first thing is dont try and figure out how anything is worked out or how decisions are made at the college of knowledge.
There is, or appears at least to be no logic or reason to anything that happens down there and i dont think anyone actually knows either.
The best thing to do is work hard, keep your head down and dont piss anyone(instructors) off. Best of luck with the course anyway.
Oh yeah and hope you dont have to meet a 'woman' who seems to bathe in cheap perfume.
if she is still there that is.
