Keep in mind accuracy can be a misleading indicator because apart from your own knowledge, accuracy also depends on the level of difficulty of the questions. It'll be higher on the easier questions (PR 2007) and much lower on the tougher ones (Kaplan800
CR's and SC's almost had me depressed).
With that out of the way, these threads might be of interest to youhttp://gmatclub.com/phpbb/viewtopic.php?t=30989http://gmatclub.com/phpbb/viewtopic.php?t=29703
My accuracy on DS was pretty high by my standards. In the OG-11 Diagnostic test I only got 1 DS wrong and that too was because of lack of concentration not lack of knowledge of concepts. I then did the last 20 DS questions in the practice section in OG-11 and got 1 wrong because I didn't think hard enough to get to the solution. I gave up too easily. In the Kaplan800
DS's I think I got 3 wrong. The Kaplan800
DS technique is good.
I never checked accuracy in PS. For PS I believe given sufficient knowledge, if you can understand the question (and identify the subtleties in some cases) you willl almost always end up with the answer. I did this because I found advanced level GMAT PS wasn't as hard as some might imagine but the questions were presented in a twisted way.
I practised a RC a day and once I had found the right RC technique for me I would generally get all of them right except some passsages where I got 1 or 2 wrong and they were mostly due to lack of focus and rarely due to the complexity of the passage.
In CR's, on the few dvtohir ones I tried my accuracy was an enviable 0%! (I can say that and be happy about it now
) and less than 50% on Kaplan800
but that was before I had worked on my CR technique. So later my accuracy was higher than before but not extremely high. I did 5 CR's a day towards the end and would get 1 or 2 incorrect, mostly because of their higher difficulty level (they were tougher than the ones I saw on the GMAT). I had got these CR's from my prep classes and they were nearly as tough as dvtohir's. I believe it's a very good idea to practice on the toughest CR's using a good CR strategy. GMAT CR's seem a lot easier this way.
I got very few SC's wrong in OG-V and in OG-11 SC's (which I did using MGMAT SC
) my overall accuracy was, I'm guessing, between 85-90%. Kaplan800
SC's would have been around 60 - 65% but I learnt a lot from their SC's.
These accuracy levels are what I was at about within a month of my taking the GMAT. Also you must understand that I was always trying make the most of my mistakes. Always trying to learn from them and I learnt more from the ones I did wrong than from the ones I did right. So after going wrong on about 35-40% of the Kaplan800
SC's I had improved a lot. Thats just to say that if you are at the same accuracy level I was at doesn't mean you'll score the same as I did unless you learn from your mistakes the way I learnt from mine. Yep, that was a warning that accuracy can be misleading.
Lucky for me you asked this question while I'm still fresh from the GMAT and have't forgotten these details
Good luck and see you around at the forums
