I took the PCAT back in 2010, so take what I say with a grain of salt. I was an idiot and thought you could use a calculator. I brought it with me and was shocked when they said it couldn't be used. Anyway, I didn't get to answer the last quarter of the math questions -- just not enough time. I left and almost had a panic attack (no preliminary score reports could be provided for the written test). I had never taken a standardized math test before and not gotten a perfect score. Anyway, it all turned out okay, and I scored in the 90's for that section, despite leaving a quarter of the questions blank.
