OOS students can be, and are, accepted every year without fulfilling the VPA requirement. But, if you can fit it in, you should, because admissions chances are likely better having fulfilled the requirement.
A one semester CC class will fulfill the one year VPA requirement…is that an option in the summer, or concurrently during second semester junior year, or senior year? There are online purveyors of classes that satisfy the VPA requirement as well (check UC system websites for links). Perhaps @Gumbymom can weigh in as well.
Good luck.
