Sorry to be a downer but as per 2018 trend, CRS cut-off score can only go up from here. Remember, 2018 started with 440 and ended the year with 445. If the CRS cut-off score right now is playing around 445-450, then by the end of the year it's going to be 455-460.
With the federal elections in October and the impending decision on Spouse work visa in the US, the CRS cut-off score might increase to 460-465.
So for those who have the money to do so, please work on increasing your scores right now or seriously, seriously think about student visa options! (and also pray a lot that magically the pool decreases and people lose interest in migrating or that Australia magically loosens up its immigration rule since it just voted a pro-immigration PM)
