ok great thanks for your reply. this whole thing is quite confusing as there are so many options, so many books etc. out there.
in your 3 mth guide it says take a practice test first before studying... wouldn't this waste a valuable 'official' practice test though if I've done no preparation so far, or is it really valuable to ID weaknesses? Alternatively, would the GMAT club diagnostic test provided in these forums be a good start instead of a practice test?
thanks again
Good Question!
yes, you would use up an official practice test but you have a few of those (at least 2 but more like 4). Here are the reasons that I would recommend taking a GMAT Prep at the beginning of your prep:
1. You get a clear picture about the test, interface, procedure, process, etc that some of the other tests do not provide
2. You get an accurate measurement of your performance (which again can be off with non-official practice tests). This is very helpful to track your progress
3. When you take a practice test at the beginning of your prep, you will most likely score between 500 and 600 (that's Ok if your score is lower); hopefully by the end of your prep you will be scoring 650+. If that's correct, the overlap of questions that you see during your diagnostic test at the beginning of you prep and the end is very small. Thus, you can take 2 official tests and then reset them and most likely not encounter any repeat questions in your second attempt. Overall, there are 1,000+ questions in the gmat prep (800 math questions and close to 200 SC's).
All of this combined together suggests that it's not a waste of a practice test to use GMAT Prep as a diagnostic.
