Quant Geometry

@Netprotox, the solution to mastering tough geometry questions is not avoiding them. When you identify a weakness, you tackle them head on. You focus your attention on that area, and put in extra efforts in order to overcome it. You hit it hard until it becomes a strength. Preparation for the GMAT can be very daunting with highs and lows, and your approach in managing the lows will go a long way to determine how well you perform on the actual test. Don't be in a hurry, take your time and master every aspect of the GMAT quant if your aim is to attain Q51. Last but not the least, have an open mind towards the tougher geometry questions, because an open mind will help you to comprehend the solutions posted by the math experts and other forum members who are able to solve the difficult questions.

Have you done some targeted studying regarding Geometry, or have you just tried practice questions? I'd recommend picking up the MPrep Geometry study guide for both reading material and specific Geometry exercises.

It's not clear to me why other posters above think you're aiming for a Q51, but if you are, a Q51 would be almost impossible (impossible without extraordinarily good luck) if you didn't know much Geometry.

Considering how big a topic Geometry is, it's actually not tested all that often, but it shows up often enough that you can't really get away with not learning it. If you can't answer 500-level Geometry questions, say, then as Mahmoudfawzy83 says above, you're taking a big risk. On some tests you take, you won't see many easy Geometry questions, and then it won't hurt you so much if you get those questions wrong (since getting hard questions wrong isn't that bad on an adaptive test). But on other tests, you'll be guessing at easy and medium Geometry questions, and without very good luck, you'll really be hurting your score. That's the much more likely situation. If you take several tests, I think you'll find your Quant scores are much more volatile than average if you have one glaring weakness in a certain-to-be-tested topic.

Geometry requires more memorization than any other subject -- you need to learn area formulas, Pythagoras, etc -- and it also often requires a different way of thinking than other subjects. So you should, as ccooley suggests above, be learning the theory of the subject first, before doing practice problems. So I'd suggest you find a good Geometry book to use (mine if you want a high-level book, another source if you want an easy/medium book, which is probably what you need right now) in conjunction with a good supply of official practice problems.
