i think with physics and chem. the teachers who answer questions for options, prolly never taught it yet....so yeah, thats why they might not b able to answer questions from the options sometimes.
Nah..I rang up for modern history to ask about nationalist leaders and the guy didn't even know/teach Indochina...hense gave me the wrong answer after a lot of "ummm" and "hmmm" .....no wonder they give that warning thingy at the beginning that the information may not be correct or whatever
yeh... but i mean they oculd make it easier and know what teacher have taught what. if you do sumthing that one of them hasnt taught then you can still get put through and see if they can help. otherwise you end up with a guy like i did telling me to look at study guides.
