Hola Jasmine

Yes, the preposition "a" in Spanish is used in many different cases. For some of the most common basic level uses of "a" see this lesson. And some extra lessons are for example:

Spanish personal "a" verbs (ver, visitar, buscar, conocer)

Using preposition "a" to indicate how/in which style something is done

I hope they help.

Saludos cordiales
