Is Pearson PCAT practice test scaled?

Hi everyone, I'm a little confused about the Pearson practice PCAT test scoring. it gives me the highest range on all my sections, while it actually shows mid to high 80s on every subtest. So I was wondering, does Pearson test take into consideration previous national average scores? I've been pretty consistent with the number of right/wrong answers so I'm wondering if my Pearson 85th percentile could actually go into 90s on the test day.
