I finished the test in well under 25 minutes and got my results. They are in line with other tests I've taken over the years but there was a lot more detail which made this test more valuable to me. Surprisingly accurate considering it only takes 25 minutes. A good blend of various questions to really make your brain work quickly and flexibly. Excellent evaluation aimed to give you the most up to date and accurate IQ measurements out there! 100% recommend this product!
