Thanks for the replies
As I said, I wanted to know if the color was the same because I am taking paper versions of the practice tests. I wanted to simulate the MCAT experience as much as possible.... is this going overboard? Not from my perspective. I am the same person who:
1) called the MCAT people to see if it was ok to go into the test w/o makeup on(because I took my driver's license picture w/makeup, and I was worried I would look different and would be denied entry if they couldn't make a "positive identification"). For girls who have similiar concerns(although there probably aren't any as paranoid as me) their recommendation is to go ahead and wear the makeup, if you think you look different from your picture.
2) called the MCAT people to see if I could buy their "noise reduction" headsets from them(answer: no, you cannot, and they don't know where Prometric gets them either)
I have many other paranoia issues relating to the MCAT which I won't go further into.... but I don't think asking about the coloring of the highlighting was too extreme, at least for me.
Anyway, good luck everyone and thanks for the replies
