Thanks for your answer,
" Regardless of whether you fall on that spectrum, I think it's a terrible idea to actually use your IQ to decide whether you should study math- no matter how good a predictor it is, your actual math performance is an even better one. "
Got to agree on that first part, I thought the same when I was younger ; I've actually already started studying. My biggest issue (and the reason behind this) is that my work and investment (3rd year undergrad math, at a very good french university) are seemingly unrelated to my ...
I meant the "Perceptual reasoning index scale" in particular ; I don't really care about verbal score as I doubt it could be a limiting factor for me. The 2 others indexes (working memory, processing speed) might be important but I will give them importance only if the score for perceptual reasoning is already high enough.
(using the WAIS-IV, performance IQ is indeed an older concept)
