You studied hard. The score didn't show it.
Think back to PT school. You walk into office hours to go over a test, and you can explain the right answer to almost every question you missed.
Your professor asks the obvious thing: "Then why didn't you mark that on the test?"
That gap between knowing it and picking it is where most NPTE points are lost. It's very hard to see on your own, and more content won't close it.
