Hello, the new interface looks great. You've done a great job. Here are a few of questions, I hope noone has asked:
- Are the questions within the free access computer adaptive or only when you purchase? I feel I read somewhere they are but after going through some I didn't feel they got progressively harder (this is the case when I would have mutlpile questions right in a row).
- How did you come up with the CAT algorithm for the questions - on your own or using a third party? I'm curious as to how close the algorithm may be either to the real gmat, kaplan, manhattan, etc.
- How do you report errors on questions? I went through some and noticed a couple of different problems: 1) a math syntax typo that did not allow me to see what the problem was asking for; 2) I encountered a verbal question even though I only chose quant questions for practice.
Thanks and great job, again.
