Hi Vivian,
Thanks for the response. My test date is July 23rd. I started my MGMAT course during the first week of May and have had a family vacation planned since January that will start on July 26th. If my score isn't up to par, I would consider taking it again, but would also need to know if schools look down on 4 tests in the span of 4 years (November 2011, January 2012, and 2 in 2014). My DO OR DIE score is around 680. I felt like a 60 point increase would be very manageable, especially with a lower verbal score. The two schools I am most interested in are Georgetown and University of Maryland. I currently live in the DC area, and I don't plan on leaving, so I am restricted to GU, UMD, GWU (Undergrad Alum), AU, GMU, Catholic, etc.
What are your strategies for systematically approaching the following question-types: DS, PS, CR, SC, CR?
For DS, I break down/rephrase the problem (clean up/simplify messy equations, state if its an integer), build a t chart for statement 1 and 2 (to prevent statement carry over) as well as build a box of AD/BCE for eliminating answers. I then work through statements 1 and 2. I don't really change up my approach for Value vs Yes/No except when I work through the questions, I say "does this equal x" or try to prove if the Yes/No can be the opposite or conflict (yes and no).
For PS, I determine what the problem is asking, and use the appropriate topic (combo/prob, triangles/quads/3d, algebra, FDP, etc) to solve.
For RC, I read the passage. For Specific Detail questions, I go back into the passage based on the question and find proof for an answer. If there isnt proof in the passage, then the answer is generally wrong. For Except questions, I work E-A, otherwise I work A-E.
For CR, I try to find the Reason and Conclusion for each question, then work through the answer choices from there. CR was a weaker area prior to Test 3, but I saw improvement on my 3rd CAT because I focused on that area a little more.
For SC, I look for splits in the answer choices. Based on what is being tested in the question, I look to see what the modifier is next to, if there is subject verb agreement, parallelism matches up, etc. Idioms are something I'm just now studying. I've downloaded the Magoosh flashcard apps and will also be looking into the BeattheGMAT flashcards.
Pacing wise, on my 2 live tests and first 2 CATS, I would finish each section with 15 mins of extra time, however, I found myself strapped for time on the 3rd test. I guessed on a bunch of questions near the end to finish the Quant Section.
Do the GMATPrep tests allow for review? I've avoided them at this point because I didn't know if I would be able to review them after finishing. I'm very interested in seeing question level and how my progression through the test went (where I dipped down or climbed up, how far each way, average difficulty, etc).
Thanks again for the response. I appreciate it!
It's also possible your strategies rock but you don't have a handle on the tested content or are really all over the place when it comes to pacing. 
) review ALL your GMATPrep exams thoroughly, knowing how and why you got each Q incorrect. They do not provide full explanations, but you can find them easily enough via Google. The GMATPrep doesn't do the hard work for you the way test prep companies will but these questions are worth their weight in GOLD. A lack of review will kill your progress.
