i had a voucher and i had to spend at least $100 on these stupid lectures otherwise i couldnt use it. so i picked eco as a 'spacefiller' kinda thing. silly me. i'd already gone to the January one and it totally sucked (my friend and i played naughts&crosses at the back lol) but i was willing to give it the benefit of doubt XD no such luck... i'm never going back!!!
