some of the diagrams are very out of sync with the true problem (wrong angles and dimension ratios). I used to work for Stanley K and was even invited to go to NYC to work on problems. Something is really wrong here. I scored in the upper 99th percentile on the GRE math back in the early 70's. I am a Latin teacher who just gave the site to her students and was devastated when I saw the problem problems. Inexcusable! It was easier for me to contact you than them, but I will keep trying. Shame on someone! I work with ETS.

I was not credited with a few thou grains from last night, but the problem with the incorrect problems is exponentially more concerning.
