MAT scores are normally distributed with a mean of 400 and a standard deviation of 25. z = (468-400)/25 = 2.72 Pr { N <= 2.72 } ~= 0.9967 IOW, percentile is about 99.67.

A 403 on the Millers Analogies Test MAT is a 45.2 percent. This is calculated by the flowing: 375-405 scores are -3, -3/25 - -.12 Standard Deviations, since the MAT has a STD Dev of 25. The cumulative area for a Z score of -.12 is .4522
Basic vocabulary and a brush up on The Classics would get you that score.

mean: 400std deviation: 25z-score = ( 380 - 400 ) / 25 = -0.8The probability of getting a score lower than this is about 21.1%. Or, in other words, about 78.8% score higher.Please see the link.

If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation
The average score on an IQ test is about 100. If you score higher than that, your score will be above average.
The formula to derive the AFQT "raw Score" is 2VE + AR (Arithmetic Reasoning) + MK (Mathematics Knowledge). This formula results in the AFQT "raw score," which is then converted into a percentile score. [cited from ABCs of the ASVAB. pg 3. by Rod Powers About.com]
