¿Sí? ¿Quién es?

Spanish uses an opening mark:

- ¡ before an exclamation
This helps you recognize the tone immediately.
Notes explain it. The conversation makes it stick.
In Formula 100 you hear each phrase in a short scene first, then recall it from memory. The phrases come back in your review deck just before you’d forget them. From Week 2, you also rebuild each conversation in Spanish a week later.
