The quant supplemental guide has a whole batch of new questions. However, the format of the supplemental guide is identical to that of the official guide. There are about 300 extra practice questions, but only about 50 problems near the end of each section are difficult 700+ level questions. Thanks...

700+ Level Questions / OG Guides
Where can I find a good source of 700+ Level questions? I read in the recent article on here that the OG is not the best source. Any ideas? Also, does the OG Quant guide (the one with ~300 problems) have completely different problems from the OG12 Guide (the one with 900+ problems) or is it basicall...

Better to Raise My Quant Score or Both Quant / Verbal?
On practice tests I generally score around the Low 40's in Quant (~70%) and high 30's (~85%) on Verbal for a cumulative score of about 650. My goal is to get a 700 or greater on the actual test. Is it more advantageous to focus purely on raising my Quant skills or should I try to raise both. Keep in...

(x-3)(x+3)/[(x+9)(x+1)] or Is (x+9)(x+3)(x+1)(x-5) > 0 1. x < -3 2. x > 5 B is sufficient. Can you explain how you went from (x-3) (x+3) / (x+9)(x+1) to (x+9)(x+3)(x+1)(x-5)>0? I do not see it. Also, can I break down your statement like this: x/(x+9) > 1/ (x+1)--> x/x+x/9>1/x+1/1 --> 1+x/9 > 1/x +1...

OG 11 DS Questions
I just completed all 155 of the OG11 Data Sufficiency questions and got 134/155 correct. All questions were done in a timed environment (2mins per Q). Is that considered good? Should I be happy with that? Do I need to work harder on DS until I am able to get over 90% correct? Any thoughts would be g...

I actually got different answers. Like the post above though, I do not want to post all of my work only to find out I am wrong. My differing answers are: 1)C 3)B A brief overview of why I think C works for #1 is because in statement 1 you can move things around and get x=y+1/2 Plug that into stateme...

Statement 1 says that 2a has exactly 3 factors. You should know that only perfect squares have 3 factors, so 2a is a perfect square. Since 2a is a perfect square, you know that a cannot be a perfect square, and cannot be prime as well. This statement is sufficient. Ans: A I agree with your answer, ...
