hey i saw ur message. lol when i got those preditions i was kinda disappointed but i realised those were just estimates and no matter what their estimate of my uai it doesnt really matter, so i just continued and tried my best =) my exteranl marks were around 2 marks higher then my internals, and i think they improved because i started using the syllabus properly and hence studied smart instead of just hard =P and yes my cohort was relatively strong, we jumped from 170 in 2007 to 90ish in 2008 in terms of ranking. Cheers =D
