🧵 Processing Speed

I took the WISC when I was 13 and scored around 140. IIRC I got above 140 on the visual spatial and fluid reasoning subtests, and I think 130s on the verbal index. My memory was somewhere in the 120s-130s and my processing speed was the lowest at around 120.
This would put my speed at about the 90th percentile, but I attended an above average high-school and was consistently one of the fastest test-takers in my classes (especially for math). Say my high school was the top 50%, and I was in the top 10% of my AP/honors classes, which were the top ~25% of the school.
Even now in a high-tier college I still usually go through exams quickly and often understand concepts faster than my peers, even if I don't study too hard and as a result get only slightly above average grades (which I'm completely fine with).
So is the WISC processing speed test a poor estimate of real-time processing speed? The memory and reasoning scores are definitely accurate, I have a good but not exceptional memory. My hunch is that while taking the test I took time to double and triple check my answers on the processing speed tests. Giving snap answers typically makes me anxious.
If you've taken an IQ test, how was your processing speed? Do you think it's accurate?
