lol thats a quite random number =)
my chemistry teacher plays WOW XD and she takes like a month to mark a test/assessment
we waste half of our lesson talking about her weekend and who she is gonna invade on WOW with her friends, im changing the previous grade i gave her before to...3.5/10
she is helpful...sometimes
physics teacher helps whenever we ask, marks tests/assessments day after done, knows his stuff and is the smartest guy i know =) and he's only staying this year so we have a phys teacher(he's 59 and is retiring) and deserves 10/10,
the year below mine has my chem teacher for phys hahahahhaa she hasnt done phys since uni 22 years ago
