About Stanford IQ Test-II
What's the difference from the first set?
The second set increases to 40 original questions, with 8 questions in each dimension. The question volume and sustained concentration requirements are higher, and it is suitable for continuing advanced practice after completing the first set.
Are practice references equal to formal IQ?
Not equal to. The reference value is only generated based on the correct number of the original questions on this page, and does not use standardized age norms or professional testing procedures.
Can learning ability be judged by results?
It cannot be judged alone. Learning performance is also affected by various factors such as knowledge and experience, motivation, sleep, emotion, language and educational environment.
