I took 4R last week and 5R today...my scores on 4R were 12V, 9 BS and 8 PS, and my scores on 5R were 12V, 11 BS, and 6 PS (!). I did all my BS studying last week in after taking 4R, so I was glad to see an improvement in that section, but my PS score on 5R was the lowest I have ever gotten.
I'm kind of freaked out about it, I was getting 7-8 in PS and hoping to bring that up a couple of points before the real thing to a 9 or 10, now I'm worried if I'll be able to do that or not. I ran out of time on that section and had to guess on the last 10 or so questions, so obviously I need to pace myself better on PS (this isn't the first time that's happened, although I don't think I've ever had to guess on so many before). I'm glad to hear that others found the PS on 5R difficult also, makes me feel like less of a ******. As far as VR goes, this has always been my best section, but I disliked it on both 4R and 5R for different reasons. On 4R, I thought the scale was a little tough--I only missed 5 questions, which earned me a 12, while missing 6 questions in that section on 3R was a 13. On 5R, I would agree with others that there were some very ambigous answer choices. BS seemed comparable on both tests to me.
When I was entering my scores into the e-mcat site (I bought the online access, then printed out 5R and took it on paper, then tediously entered my answers into the site for computer scoring), I felt so tense and kind of pissed off that this test makes me judge my self worth by a couple of points difference in one section. Every time I entered in an answer and a little red "X" came up instead of a happy blue check mark, I cringed inside. I couldn't even really be happy about the significant BS improvement because my PS scores were so crappy. I haven't really stressed about this test too much until the past couple of weeks, and I'll be so glad when it's over, I just hope I never have to take it again. Sorry, just needed to get that off my chest.
