How do you say what are your grades in all class and where is my candy at Spanish?

There's no single perfect translation as the phrasing depends on formality and context. Here are a few options:

Option 1 (Informal):

* "¿Cuáles son tus calificaciones en todas las clases? ¿Y dónde está mi dulce?"

This is a fairly direct translation and suitable for speaking to a friend or someone you know well. "Dulce" is a general term for candy.

Option 2 (Slightly more formal):

* "¿Cuáles son tus notas en todas las clases? ¿Y dónde está mi caramelo?"

This uses "notas" (grades) instead of "calificaciones," which is slightly more formal. "Caramelo" is a more specific type of candy, but can still be used generally.

Option 3 (More formal, emphasizing all classes):

* "¿Podría indicarme cuáles son sus calificaciones en todas sus asignaturas? ¿Y dónde se encuentra mi dulce/caramelo?"

This option is much more polite and respectful. "Asignaturas" means subjects. Using "podría indicarme" ("could you indicate to me") is a polite way of asking.

Remember to choose the option that best fits the situation and your relationship with the person you're talking to.
