So I just recently took the WAIS-IV as part of an ADHD assessment and was surprised at the scores. I know most people here talk about their kids, but I'm just curious about what others think. I went in for testing on less than 5 hours of sleep (which I have been struggling with lately) and I had literally just gotten out of an exam for college so my brain was fried. The scores I received are as follows.

VCI - 120 91st percentile
PRI - 111 77th percentile
WMI - 117 87th percentile
PSI - 100 50th percentile
FSIQ - 115 84th percentile

Subtest scaled scores

Vocabulary - 14
Information - 14
Similarities - 13

Matrix reasoning - 14
Block design - 11
Visual puzzles - 11

Digit span - 13
Arithmetic - 14

Symbol Search - 10
Coding - 10

My psychologist said that I had mild, inattentive type ADHD and that I struggled with visual-motor integration on timed tasks. All of the tests that weren't timed I seemed to do much better on with the exception of arithmetic. I also have a diagnosis of Generalized Anxiety Disorder.

What was strange was the PRI score and the scores on Block Design and Visual Puzzles. I have always excelled in mathematics and science scoring anywhere from the 90th-98th percentile on achievement tests in these areas, so I don't understand how the PRI was only 111. I did a lot of items in the visual puzzles subtest and the only item I couldn't complete in block design was the last one in the subtest (I know this since I remember reading somewhere that BD had 14 items and the last 5 were 9-block designs which I did 4 of). I would have expected the PRI to be at least 10 points higher than the VCI, not the other way around. Aside from matrix reasoning, these scores don't make sense to me on the PRI.

I've always been a fast learner. I taught myself calculus in 9th grade and my Spanish teacher wanted me to learn the 2nd year of Spanish over a summer because I breezed through the 1st year. I've always had a fairly advanced vocabulary and was using words like oscillating, excavator, and actually at the age of 3. I was reading before I was in school and I had expressed an interest in skipping grades or acceleration when I was younger, but never had any testing done to see if I could.

Could the factors I mentioned (lack of sleep, brain dead from an exam, ADHD itself, anxiety) have lowered my scores?
