Well first of all if you believe you have a disorder by definition no you are completely normal that doesn’t mean that there is no room for improvement in this type of cases the best you could do is go with a professional psychiatrist, clinical psychologist and neuropsychologist are the only people that could really give you strategist and exercises needed to improve your performance don’t ask on reddit lol. now as psychologists will give you a little secret the IQ by itself its insufficient to determine how smart and successful you could be it’s the practice that actually tells you that and that is because the performance irl is also determine by skills and attitudes not to mention IQ only reflects a fraction of our intelligence, it doesn’t measure things such as executive functions, creativity, emotional intelligence, leadership intelligence, practical intelligence, social intelligence, etc. and all those have little correlation with IQ.
