Hi,

I have a general question regarding geometry PS questions. Whenever I see a geometry question that has quite a complex figure (for example a circle inscribed in a right triangle and the radius of the circle is forming another right triangle in the circle and we are required to find the circumference) or any such sorts, I always draw the figure and then work out on my question.

I need to know whether this is a right move when I writing the actual GMAT.

Please let me know.
Thanks.

For complex figures, I typically draw the figure.
I think it's worth doing.

Cheers,
Brent

I think it's pretty much essential to redraw the picture when you're working on geometry problems. Often, you can't immediately see which identities will be the crucial ones to solving the problem, so it's best to fill in everything you know. Drawing only takes a few extra seconds (if you're not worried about drawing it perfectly), so don't worry about it taking too much time.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
