GMP1, saw a lot of repeats, raced through it, each section in 30 mins. Also only slept 4h/night the last two days.
I have to review some more trig, saw a hard 51Q geometry DS.
770
51Q (5 wrong) - I remember I got a really, really simple DS wrong. Argh!!!!!
44V (5 wrong) - Saw a passage again that I didn't read, tried to "remember" the answers, got 2 wrong there. Also got 2 SC's wrong that I should have spent more time on. I forget the other one.
Didn't read a lot of questions..... argh. The repeats are killing me because subsconciously I think I remember the answer, so it biases me. Most of the math, if I worked them out, I'm pretty sure I would have gotten right, so I should be OK on the real thing.
Ok, so I'm convinced GMAT takes into consideration the # of questions you get wrong.
Even if you were to score a 51Q and a 51V, you'd most likely get a 790, unless you got 0-1 wrong. You can get a 51Q even with getting apparently up to 5 wrong! As long as you get the impossible ones right most of the time, the 51Q's, you're OK. But you'll be penalized with perhaps a 10-20 point deduction for sloppiness. I also noticed GMP1 scaled the questions very quickly. I was on 50-51Q questions by the time I got to question 7 or 8.
I'm not sure about the verbal, but it scales harder I believe.
Anyways you can get a 770 while getting 10-12 wrong.
I'm guessing a 780 with 6-8 wrong, and a 790 with 3-5 wrong, and an 800 has to be almost a flawless performance.
I'm assuming if you get a hard 51Q or 45+V you can get it right.
Just some things I noticed today.
