NAU got back to my kid in a couple of days. It is $40 for a simple application and gave my kid piece of mind.
As others have mentioned, give Monterey Bay a look. I would also visit Merced. When you say “all UCs” I’m not sure that Merced would be a good fit for a kid who is interested in SDSU or UCSB. That said, UCM added some new business majors and have announced that admissions decisions will be released in December.
