High school diplomas obtained in Canada or the United States are usually acknowledged as a "Mittlere Reife" (graduation from a "Realschule"). In some cases however students may apply for certain subjects at a university. All students holding an American high school diploma may apply for the "Studienkolleg", and after successfully graduating from this they may attend a German university. Those holding a high school diploma can choose from a wider range of possible major subjects at a German university if they did well on the SAT or ACT. Those who scored higher than 1300 on the SAT or higher than 28 on the ACT may apply for any subject at a German university.
