You'll actually get replies sooner if you don't respond to your own post - we answer questions starting with oldest posts first, so when you respond to your own post, you put yourself later in the queue!
Also, as you may have noticed, the forums are quite large and we are answering a lot of questions. It's very unusual to have a question answered in less than 12 hours. It typically takes 2-4 days in this folder, and it takes longer in other folders.
You're not doing anything wrong. Your GMATPrep scores were inflated because you had repeat questions (questions you'd seen before). The inflation is two-fold; first, you likely already know the answer to the question and, second, you can answer the question very quickly and then you have extra time that you really should not have had.
You can still take such tests as long as you follow a few guidelines to minimize the chance of artificially inflating your score via question repeats. First, anytime you see a problem that you remember (and this means: I know the answer or I'm pretty sure I remember the answer, not just "hmm, this looks familiar..."), immediately look at the timer and make yourself sit there for the full length of time for that question type. This way, you don't artificially give yourself more time than you should have. Second, think about whether you got this problem right the last time. If you did, get it right again this time. If you didn't, get it wrong again. If you *completely honestly* think that you would get it right this time around if it were a new question (even though you got it wrong last time) because you've studied that area and improved, then get it right this time.
When did you take these practice tests? Did you take them all in a short period of time? (Anything more frequent than once a week is a short period of time.) The overall test scores are pretty consistent (within the standard deviation of these kinds of tests) but, as you noted, the quant and verbal subscores are fluctuating a bit.
So, first, CAT exams are really good for (a) figuring out where you're scoring right now, (b) practicing stamina, and (c) analyzing your strengths and weaknesses. The actual act of just taking the exam is NOT so useful for improving. It's what you do with the test results / between tests that helps you to improve.
When you review your work on verbal, here are some questions to ask yourself:
- if you got it wrong, why? what tempted you to pick the wrong answer? why is it wrong anyway? what tempted you to eliminate the right answer? why is it right anyway?
- if you spent too much time, why? specifically, which part of the problem? did that extra time help? did that extra time hurt on a later problem? (if you spent more than 30sec over, the answer is yes, even if you got this problem right) how did that extra time hurt? specifically, where did you then not have enough time?
- if you spent too little time, why? were you rushing b/c you were behind? why were you behind; on which ones did you spend too much time? or did you think the problem was easy and you didn't need that much time? how often did you make mistakes on those "easy" problems on which you felt you didn't need full time? (On problems like that, you should make almost no mistakes - 95%+ accuracy. So if it's anything lower than that, you're hurting yourself by choosing to go fast when you think a problem is really easy.)
You can apply the second and third sets of above questions to quant problems as well.
It would also be nice to figure out why your score is fluctuating. Are you having some timing issues? What about your stamina? Are you taking the tests under full official conditions (with essays, 10-min break only between sections)? Are you taking the tests at the same general time of day as you plan to take the real test? Are you NOT taking a bunch of tests multiple days in a row?
