Before answering the OP it would be helpful to have a operational definition of intelligence for this question? Are you strictly referring to Binet IQ test like measures and other such standardized western style intelligence scales? Or do you want a qualitative estimate of some sort?
Keeping this uncertainty in mind I will now attempt to make a vague estimate of my intelligence. Keep in mind that a IQ scales and other standardized test for people of typical neurology are less useful for judging my personal intelligence do to having minor anatomical and neuroarchitechtural abnormalities do to premature neural development at birth, and suffering from aspergers. Having said that lets move on to a estimate of intellectual functioning.
Results of IQ test going into university.
-Average was roughly 107 over multiple scales. Highest was 115 in spatial memory and reasoning. Lowest was in various math and language scales. lowest was 90. Moving on now to academic performance.
Grade school:
Showed attentional problems and sever agitation at having to do repetitive tasks. On more then one occasion showing aggression towards teachers do to frustration over assigned material, often unable to keep up with other students in speed based assignments and measures. Did not learn to read till 5 years old, decided to teach self to read do to frustration with not being able to, reached age appropriate mastery after 1 month of dedicated effort, minimal understanding of reading English up to that point. Eventually was sent to a SLC class for disruptive students at age 9....... no progress or notable academic advancements, in fact do to negligence in scholastic program of the SLC class, I was held back 1 year (Not based on academic performance?). Parents, and child (Me) decided to forcefully withdrawal from program after 3 years in favor of home schooling in order to reach academic levels necessary to enter high school (Level was reached and surpassed in time for high school).
High school: Received 3 academic awards during stay in high school, for social studies, french, and history, didn't fail any class during 4 years of high school, and in fact went back to take night classes to get the few courses that I didn't have time for.
1 Year break to try to raise funds for university/vehicle.....unsuccessful.
University: First year (Failed English 100) Passed in top 80th percentile in biology 100, Psych 100. 2-3 Decided not to peruse pre-pharmacy in favor of pursuing a future in parapsychology. 4th year. (Made deans list for summer semester, received diploma of arts, and bachelors in psychology, applying for honors to pursue masters studies).
So as you can see its not a clear picture whether I am dumber or smarter then any given human being. For I can when I find something interesting, memorize advanced diagrams and theories that very few individuals are able to, yet I have slower then average processing speed of certain streams of information, and a generally reduced ability to replicate data physically or verbally, also I demonstrate minor deficiencies in dialectical memory (Names of people in particular).
In short my liquid intelligence is about average or slightly below, but my christalized intelligence is often far superior to most in my age group. Does that make me intelligent? Damned if I know.
