Physics SPM Trial Paper

OMG...today every form 5 student in the science stream in our school, if not the whole state, had to take an all-challenging paper called physics...though we had tips beforehand but damn!!! whats that with the paper 2 thing? question 8...whats that all about anyway? LDRs, lamppost, transistors...etc...etc...can't make head or tail out of it...haha...however, apparently some people like lai jia hong actually loves the paper! (OMgawd) well...is over now anyway...so gonna try to forget bout it concentrate on tomorrow's chemistry paper...hope it would be a breeze...but, lets not get our hopes too high=)
