Oakville High School senior Ian Darnell is in an academic league of his own.

Darnell recently aced the history subsection of the SAT II college entrance test, scoring a perfect 800. The SAT II subject tests are not as commonly taken as the ACT or SAT I tests, but are required by some universities, according to a district news release.

The perfect score on the history subsection wasn’t the first time Darnell aced a section of the college entrance exams. On the October ACT exam, he scored a perfect 36 on the English section of the test and earned a 35 on the reading section. His overall ACT score was a 31. He also scored a perfect 36 on the reading section of the ACT exam when he took it in June.

Darnell, 17, is the son of Robert and Colleen Darnell.
