Cultural Tip
In many Spanish‑speaking classrooms the phrase is informal but polite; teachers often add a smile or a slight pause to signal openness. In more formal settings you might say “¿Alguna pregunta, por favor?” to keep the register higher. Remember that “duda” can sound a bit more personal than “pregunta”, so using “pregunta” is safer with strangers.
