Nobody can tell you that. All people can do is make predictions based on things staying the same, and if things stay the same, the answer is no.
When Harper was PM, there were a bunch of people asking the same question - I'm at 448, will I get picked? People told them to wait, saw that the scores were dropping for a while, and assumed it would continue. People were predicting sub-400 scores, insistent that the scores couldn't go higher. They did, and 460 might be the new 400.
If you want the highest chance of coming to Canada, then the question is not whether the scores will drop enough to pick you, but what you can do to get your points up. Are you eligible for PNP programs? Can you improve your work scores? Language scores? Are there things you can do to become one of the 700 people they pick in a draw?
