✕Common Mistakes

Quando é a tua prova de ciências?
For future events many speakers prefer *será* (future of *ser*). Both are correct, but *será* sounds more natural when the exam is not yet happening.
Quando é o teu prova de ciências?
The noun *prova* is feminine, so the possessive must agree: *tua*, not *teu*.
Quando é a tua prova de ciência?
The subject is *ciências* (plural). Using the singular *ciência* changes the meaning to 'science' as a field, not the school subject.

Cultural Tip

In Portugal and Brazil, *prova* is the common word for a school exam, while *teste* can also be used for shorter quizzes. The possessive *tua* is informal; in a more formal setting you would say *sua* (e.g., *Quando é a sua prova de ciências?*). Also, Portuguese school timetables often list *ciências* as a single subject that groups biology, physics and chemistry together.
