Hi,

I just did Kaplan's free online test (I only got a 650 :( how does this relate to the real GMAT as I heard Kaplan is sometimes harder?) and one of the questions I got wrong was related to right angle triangles.
I knew that a 45-45-90 triangle has sides of length x-x-sqrt(2)x, but what I didn't know was the ratio of the sides of a 30-60-90 triangle. What other right angle triangle ratios must I know for the GMAT?

650 is a good score on Kaplan. Generally, one can expect 50-70 more points in actual GMAT score as compared to Kaplan score.

Thanks. Yesterday I tried to do the Manhattan GMAT free test. It was terrible! Maybe it was because I was sick, but the questions seemed very difficult (much more so than the ones in the official guide and the Kaplan test). Was this something others have noticed? I didn't get the score yet because I didn't complete the verbal section, but I know that I did poorly in the quant section.

Actually, this is no longer the case. Several years ago, we had non-adaptive online tests and paper based tests; we dropped that ball on those. However, all of our current CATs are as close to the real test as we can make them.

Still, a 650 is a great score regardless! Remember, your diagnostic is the floor, not the ceiling--there's nowhere to go but up!
