What is the highest you can score on a IQ test?

IQ ranges from 0 to 200

Here are the ranges of scores for IQ Tests and what they mean:
IQ Range Classification

140 and over ----------- Genius or near genius
120-140 ----------------- Very superior intelligence
110-120 ----------------- Superior intelligence
90-110 ------------------ Normal or average intelligence
80-90 -------------------- Dullness
70-80 -------------------- Borderline deficiency
Below 70 --------------- Definite feeble-mindedness
I've taken an actual IQ test; I scored 157. Marilyn Savant who has an IQ score of 228, was the highest ever recorded for an adult. Results may vary considering different cultures, and tests.

However, there is NO standardized IQ test that has a scaled score over 155. Your verbal and/or performance scores will scale into the 140s if you have every answer correct but your full scale will max out at 155. By standardized test I mean recognized by the American Psychological Association. Stardardization is based off the Wechsler Adult Intelligence Scale (WAIS). The MABII is an excellent example of a standardized test.
