Hi LoneWolf14159,
There's no practical way to 'translate' how you perform on a small set of practice questions into an equivalent GMAT Score - so I wouldn't try to think in those terms. It's possible that you are performing well when compared to other people who have worked through that practice material, but assuming that that is true, there's still not much to be deduced from that information. If you are interested in assessing your current 'ability level' though, then there is a direct way to do that.
Since it sounds like you're early-on in your studies, then it would be a good idea to take a FULL-LENGTH practice CAT Test (assuming that you have not already done so). You can access 2 for free at
www.mba.com (and they come with some additional practice materials). That score will give us a good sense of your natural strengths and weaknesses and will help provide a basis for comparison as you continue to study. A FULL CAT takes about 3.5 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have that Score, you should report back here and we can discuss the results.
I'd like to know a bit more about your timeline and goals:
1) What is your goal score?
2) When are you planning to take the GMAT?
3) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
