HighIQ, a few thoughts on this post:

I don't plan on taking the WAIS-IV since I know that I would easily get the maximum FSIQ and GAI and it's expensive.
1. I am answering in a new thread to avoid encouraging your highjacking of another member's thread, whose topic was Discrepancy between FRI & WMI.

2. It is unethical for someone to leak a question of an IQ test, such as the final question of the WAIS-IV Matrix Reasoning subtest.

3. Easily answering the final question of the WAIS-IV Matrix Reasoning subtest only indicates that a person had answered that particular item correctly. It does not indicate that:
- all answers given within the Matrix Reasoning subtest would have been correct,
..(I believe the discontinue rule is: after 3 consecutive missed.)
- all answers to the various Perceptual Reasoning Subtests would've been correct,
- all items on all other subtests of the WAIS-IV assessment would've been answered correctly.

4. If an adult is believed to have answered a particular item on the Adult Intelligence Scale correctly, it does not follow logically that they would've answered a similar subtest question correctly on an Intelligence Scale for Children, years ago. An IQ test is a snapshot, taken on a particular day. Even after IQ scores tend to stabilize (around the age of 8 years old, 3rd grade) IQ scores are most accurately given as a range, not as a single number.

5. Intellectual profiles are rarely even with matching scores in all areas measured. Instead, scores typically show areas of strength and also areas of relative weakness. One does not typically get a max FSIQ and GAI. Instead, the General Ability Index (GAI) is calculated only when certain subtest scores may be seen as bringing the Full Scale IQ (FSIQ) down.

6. As your posts have indicated a strong ongoing interest in approximating your IQ, and the IQ of others, the money spent on taking the WAIS-IV may be money well spent to set your mind at ease.
