hee hee my dear bio medical engineer. if u go bmt most likely go
ocs one. so fast learn how to 'por' offr liao.... 
anyway there are quite a few people from poly getting LSA. i think
my fren had average As and Bs. plus if ur grades are ok and u do
reallly well in ocs pro term, like SOM, SOH, u can actually upgrade
ur LSA to ATA. more money.... but 6 year bond...
