Cultural Tip
In many Spanish‑speaking schools the word *examen* can refer to a written test, a practical lab assessment, or even a final project, depending on the level. When asking about the exam, it’s common to follow up with *¿Cómo te vas a preparar?* (How are you going to prepare?) to show support. Also, remember that in Latin America the pronunciation of *c* before *i/e* is /s/ (ciencias → /ˈsjen.sas/), while in Spain it is /θ/ (/θjen.sas/).
