Wow, last year and this year I used the same brand of mechanical pencils (they are my good luck BIC's in metallic colors). I'm a little superstitious with those... 😛
I had no idea there was a policy against those pencils. However, my test was scored just fine last year and no one told me I could not use those pencils at the test. Several other test takers used mechanical pencils as well.
Just FYI, for those who take the PCAT in the future- at both testing sites I was offered pencils from the proctors (they read this part aloud from their "script" so I think it's pretty standard) and an electric pencil sharpener was plugged into the room.
It's always good to think ahead and be prepared. But with these standardized testing situations there is usually a back up plan in place. I'm sure if there was a problem the proctors would have made an announcement just like they did about turning off electronic devices etc. NO WORRIES 🙂
