Yes.. so only option is get another year of study... I know we only get PGWP once, but atleast you will get the points .. so even if you go back home it will not be a long while when you receive an invitation because your score will jump above 450.. ( We are assuming that the cut off scores do not go below 450 ). You do not have to study here, you can go back home and study there as well.. or work for atleast a year to bank the points for that...
