heeeeeeeeeelp!

ok. i need help. i was supposed to study general math, chem and physics at CAE in the city all in one day so i could've made it home. then they tell me i need to be doing INSANE-O, giga-nerd math to make sense of the physics and chem and the only class runs on tues. this leaves me in a fucking shit situation. last class on monday finishes 845pm then i start at 9am next day so with country train times, i would be 5 hrs at home before having to turn around and come back. and be alert enough to deal with calculus..................................... nuh.
would anybody that can spare a couch for me to crash on every third or fourth monday night (depending on how many of you can help) please let me know asap?! i'd be getting there shortly before bedtime and leaving early morning so it's hardly a social visit, but while the harvest season lasts, i can drag an esky full of farm fresh organic produce with me for the host/s as a trade... i've already spent two monday nights with the lovely teleri and jen but's can't lob on the same peeps all the time.. please let me know if you can help by ringing my home or mobile though cause i won't have internet access til next monday when i'm down here again for class, wondering whether i have to slink into that CRUSTY backpacker hostel down near spencer street that smells like vommit, late at night, paying money i don't have to prolly catch lice and get no sleep. and that's IF they have a vacancy. ugh. crappy situation. please help.
