Colonel Folsom. Yes. I will take this in sequence.
The "RV" indicates reading and vocabulary, and the score, Roman numeral II-125 indicates that he was in the second category. Categories throughout the test battery run from I to IV, with IV being the highest.
The abbreviation "AC"—arithmetical computation—and the score Roman numeral III-108, indicates that he dropped into the third class.
"AR" is arithmetical computation, Roman numeral III-90, indicates that he was at the bottom of the Grade 3 in this area.
"PA" indicates pattern analysis, Roman numeral III-94 indicates that he was the bottom portion of the third group in this category.
Now, these four areas are grouped into a general classification test score, the abbreviation "GCT" represents that definition. And as a result of Oswald's composite scores, he was graded as a Grade 3, Roman III-103. At that time, the Marine Corps average, I believe, was 107.
Mr. Ely. Would you explain the one designated "RCT"?
Colonel Folsom. The abbreviation "RCT" is—represents radio code test. There are three scores in this, ranging from one to three, with one being the highest. The minimum, or the range in Grade III is from 90 to 109. As Oswald achieved 92, he was in the bottom, practically, of Group III.
Mr. Ely. Which is the lowest group.
Colonel Folsom. Which is the lowest.
