SAT cross-tests results.

The upper part of the table shows the performance of ChatGPT-3.5 and ChatGPT-4 in both cross-tests for each of the three tests. The score obtained in each cross-test, ranging from 10 to 40, is shown in bold; it is followed by the raw score (correct answer/administered questions) and by the corresponding percentage of correct answers. The lower part of the table shows the cross-tests aggregate percentages for SAT#8, SAT#9, SAT#10, that is to say, for each cross-test, the percentage of correct answers relative to the total number of questions submitted in the three tests.
