How to take Community College Classes over the summer?

Hi I’m a 1st year, Design Major and I want to enroll in community college classes over the summer and transfer them to UCLA.

I’m going back home to Oakland, so I’ll be enrolling in the Peralta colleges there (Berkeley city college, Laney, Merrit etc.) I’m planning on getting my Quantitative Reasoning stuff out of the way so I don’t have to do it in the fall.

Srry for asking this after the crazy week we just had. But I feel kinda lost on how to approach this. If anyone has any helpful information/ stories it’d be greatly appreciated.
