Okay kids, the PCAT is scored using two sets of numbers. One set is a scaled score, and no one, not even Harcourt knows how they come up with that number. The other score is a percentage, which ranks you against everyone else who took it that go round. Say you make a 75%. That means you did better than 75 percent of the people that took it that time. And that's usually the score that everybody look at.
