Congrats on your district victory! By placing first at the event you have earned a fair amount of points that will definitely help you advance to the district championship in Spokane.
However, you do still need to attend and perform well at a second district event (I see you're scheduled for Auburn), and then if you have enough points after that you will be notified that you have qualified for the district championship.
