Hi Chris and welcome aboard. Among the given books, I would suggest you have Kaplan800, Kaplan 2005+CD and PR 2005+CD. You might also want to purchase ETS Paper Tests which you can find on GMAC.com.
Start with the fundamentals. Depending on your background, you may either need more verbal or quant tune ups. Here would be the order in which I would go about studying
1- PR 2005 will give you good tips and insights into the GMAT. It will also teach you the basics. Do not do the CAT yet.
2- Kaplan 2005 will be pretty much of a repeat. I would skip the Q+V learning sessions of this book as only its CD will be very useful. However, you ought to do the paper test provided at the end of the book as a gauge of your current skill level.
3- Go through Kaplan800 IN DETAIL. Understand how each problem is done and do not worry too much about the timing at this time. You will see that as you get better, each of those problems can definitely be done under 2 min. This is one of the best books as it will teach you how to do the toughest Q and V questions. Do not skip the explanations to a problem simply because you got it right. Go through every question to make sure that you got the most efficient way to approach it. You should go through the question banks and analyze them in excruciating detail
4- By this time, you should be fairly comfortable with GMAT fundamentals. Take your some PR CAT tests. Maybe 2 of them. Save 2 for later on. Also, do 2 Kaplan tests. Do not worry for you Kaplan scores as it is normal it will be lower than your real potential score
5- Take your first PP CD test 1 and some paper tests. This will show you where you really stand after all that studying
6- Now it is time to open up the
OG. You should not do this before the previous tests because it will contaminate your PP score as you may recognize many problems. Do every single question in the verbal section and know why you got each one right and wrong. I would suggest you also go through "the best of verbal" as there are quite good discussions on how to approach the toughest verbal problems. As for math, I would suggest you to focus only on the last 100 PS questions and last 100 DS questions of the
OG. The rest is really too easy. Do not worry if you miss like 8-9 DS in a row in the last 100 ones. Those are really tough and even many 750+ scorers get 8-9 of those wrong in a row.
7- It is now time to do the 2 Kaplan CD and PR CD tests remaining. Remember that the Kaplan test scores will be low. This is why you should avoid doing these within 2 weeks of your exam date because it will destroy your confidence.
8- Do the last PP test and ETS Paper tests.
9- Get a good day of rest and sleep before the exam.
I did not mention the
MGMAT tests because I never really used them. What you can do is split them b/w step 4 and 7. It is important that you take as many tests as possible to get the "feel" of the real exam and the time pressure involved. Also, participate in the GMAT challenges of GMATclub given every 2 weeks. It will gauge your math skills vis-a-vis that of other test takers. Last but not least, throughout all these steps, you should try to participate as much as possible in the club
This is because if you can explain things in your own words and "teach" those concepts to other fellow GMATers, it will mean that you really mastered those concepts.
Good luck,
Paul
