Is there any way to map accuracy in solving OG questions to GMAT scores( fair estimate should be fine)? I started preparing for GMAT 2 weeks back and am primarily focusing on OG at the moment. I usually solve 20 questions in each section at a time and then check the answers. Accuracy is at 60-70% in Quant and 50-60% in Verbal. Given that same accuracy levels are maintained in the real GMAT, how much score can be expected? I know that also depends on how many harder questions one solves but I am just looking at a fair estimate like 550-600. Thanks in advance for your time.
Unfortunately, your accuracy rate on the OG questions can't reasonably be translated into an actual GMAT score. For starters, the difficulty of the OG questions varies quite a bit... so getting 60-70% correct on the hard questions is much more impressive than getting 60-70% correct at the beginning of the book.
In any event, your GMAT score will ultimately determined by which questions you get right, not just by how many you get right. Even on the real test, the percent of questions that you get correct doesn't necessarily say much about your score. If, for example, you get 22/37 questions right on the quant, you could end up with an amazing score (45+)... or an absolutely tragic one. (CAT tests are pretty strange animals if you're not used to them.)
If you want to get an accurate gauge of your actual progress on the GMAT, take a GMATPrep test from MBA.com. That will test your skills under time pressure, and give you a much better sense of what test day will feel like.
Good luck!
