One of the hardest parts of learning a romance language—especially one like Spanish—is verb conjugation.
In Spanish, the way a verb is conjugated depends on a number of factors, including the subject, the verb tense, and the purpose of the sentence itself.

If you’re taking the AP Spanish exam, ser is one of the most critical verbs that you need to know—and know how to conjugate. Unfortunately, the conjugations for ser can be pretty tricky. But we’re here to help.
