Plot hole: When the students are breaking into ETS, they take great care to avoid the security cameras in the lobby; donning masks, crawling on the ground, etc. Yet a bit later, two of them go back to guard the same lobby, they are seen walking around and sitting on the desk that they so carefully crawled past earlier.ZipWin
Factual error: At the beginning of the movie, the narrator states that the lowest possible SAT score is 500. In reality, the lowest score at the time of filming was 400 (200 on each section).
Factual error: Darius says that he could ace the math section and still not achieve a 900. However, the maximum one can score on a section is 800 and the minimum is 200. For two sections, this means that he could get a 700 math and still scrape through with a 900.
