I've been reviewing the great Flashcards from this site as part of the 60-day study plan.

Does anyone know of example PS questions that use the following concepts covered in the flashcards? I haven't encountered any of those types of questions yet in my study and would like some practice with them.

1. Page 56 of flashcards - "Probability and Geometry" (If a point is chosen at random within a space with an area, volume or length Y and a space with area, ...etc. X lies within Y, the probability of choosing a random point within Y is the area,...etc of X divided by area,...etc. of Y.)

2. Page 63 of flashcards - "Use FOIL Method with Quadratics with Roots"

Thanks!

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
