No IQ Test is "30min"

IQ testing is done by a licensed psychologist and as one I can assure you that no IQ test is based off of "speed testing," yet is always "30 minutes." In an IQ testing multiple tests are done over the course of hours including timed and untimed tests that can be very hands on. This app says it can rate your IQ, but its okay, its probably only off by +/- 25 points
