Questions & Answers about Prošli tjedan imali smo ispit iz hrvatskog.
Croatian usually omits subject pronouns (like ja, ti, mi) because the verb ending already shows the person and number.
- imali smo = we had
- -li: past participle, plural
- smo: 1st person plural (we)
So imali smo ispit already means we had an exam.
You can say Mi smo imali ispit iz hrvatskog if you want to emphasize we (as opposed to someone else), but in neutral speech you typically drop mi.
