Here's an update. I just took the second Powerprep and here's what I got
Verbal 164
Quant 153: 15 correct for Section 1, 9 correct for section 2
Needless to say, I improved my Verbal but hit the wall for Quant. I'm not sure what the inconsistant results between sections 1 and 2 say about my progress. For majority of the questions that I got wrong, the math itself wasn't difficult. I think my biggest time waster was misreading a question, solving for the wrong thing, and then find out after a minute or two that I really wasn't answering the question. And the scary thing is, there was one problem (data interpretation) that where I spent too much time wondering why none of the answer choices seemed to fit. I didn't find out until reviewing that it asked for annual (not monthly) income. And despite Princeton Review saying it's a common mistake, I did forget a few basics like that the root of 36 can be -6 too (a running clock can do that to you).
What could I do to prevent careless reading mistakes? Since my test is on Saturday and I exhausted both Powerprep exams (I wish there were more ETS style online tests), what are some last minute things I can do to prepare?
By the way, here is one problem where I can't for the life of me figure out why the correct answer is right.
The perimeter of square S is 40. Square T is inscribed in square S. What is the least possible area of square T?
A 45
B 48
C 49
D 50
E 52
I answer C but the correct one is D. Why can't it be C? If each side is 7, why does that make it impossible for the square to be inscribed in S?
