AP Spanish Por vs. Para: Practice Test & Review
Por and para both translate to “for” in English, but they are not interchangeable. Para points forward — to a destination, a purpose, a recipient, or a deadline. Por points backward or through — to a cause, an exchange, a duration, or a route. The AP exam tests this in reading passages, cloze exercises, and both written free-response tasks, where a wrong preposition is one of the errors a rater will notice.
This page gives you a five-part practice quiz: an evaluation set to see where you stand, three practice sets to drill the contrast, and a challenge set to confirm mastery. Every question is built around a sentence structure that forces exactly one preposition — a recipient, a cause, a destination, an exchange, a deadline, a duration. If you get stuck, scroll down for the full grammar guide.

The Rule
Por and para both translate to “for” in English, but they are not interchangeable. Para points forward — to a destination, a purpose, a recipient, or a deadline. Por points backward or through — to a cause, an exchange, a duration, or a route. If you can ask “what is the goal?” use para. If you can ask “why?” or “in exchange for what?” use por.

✓ Gracias por tu ayuda.
Thanks are given because of a cause, so por is required.
3. Using para for a duration.
✗ Estudié para dos horas.
