This test is worth taking!
This is easily the best online IQ test I have taken. I would highly recommend taking it if you are interested. My only complaints would be: 1) Lack of ADHD accommodations. A professionally administered test would make make adjustments like time extensions, so it would be nice if such things were available here. 2) The subtests have an absolute limit at 145. If you max out a test then you wont be able to get a score with higher resolution. I understand that it can become very difficult to this, and for a free test it is a lot to ask, so its really a minor complaint.

Hello, We're happy to hear you enjoyed CORE! Thank you for the compliments. To answer your other points: 1. A professionally administered test is not supposed to have time extensions. The test manuals specifically stress on the importance of strict timings. CORE is actually more leniently timed than most professional tests as well, for example, WAIS times its items for most subtests 30s/per item, while it's 45s+/per item on CORE. 2. Most of the ceilings on the CORE subtests are higher than 145 as well! Almost all professional tests' FSIQ ceiling is 160, while it is ~170 on CORE. Thank you for your response, we appreciate it!
