First post...figured I'd give my input about the test, considering I've been reading this for a couple weeks and not contributing.
PS: I started off really nervous, but I have to admit I lucked out. I'm finishing up a PhD in physics, and it just so happens that it's in the area that was seemingly weighted a bit more heavily in this sitting. Overall, I thought it was much less calculation heavy, which I think was to my advantage.
VR: As per usual, who knows? The passages were much longer than anticipated, and although I had to pick up my pace near the end, I luckily (unknowingly) saved the easiest two passages for last. I would say the difficulty was equivalent to that of the practice tests.
BS: Once I got through the first two sections, I felt pretty great. I was expecting the test to be much harder than the practices, and I had heard that usually one section is much harder than the rest (PS seemed to be fairly challenging). This section really rocked me hard. I took my time for the first 16 questions, made sure I got them all right, but after that...I ran into a couple orgo passages and felt my stomach curl into a ball. I skipped to the end and worked backward, which I think was smart, but I really had to take some semi-educated guesses at the questions in those two hard orgo sections and about 4 or 5 discrete problems.
All in all, I thought it was rather fair, but that BS was really weird. I barely studied orgo because it seemed quite easy on the practice tests, and these questions just seemed much harder. Even for the bio questions, there were one or two that were definitely not in any of my study material. I was averaging about a 12 in the BS on practice tests, but I would not be surprised if I get anywhere in the 8-11 range.
I'm considering taking another sitting in early September, just to hopefully get a test where I don't feel like I completely failed the BS section. At the same time, I'm not sure if that's dumb or not.
