scholarships, there are lots of them out there for varying amounts and obscure demographics, so ask the high school college counselor for the most comprehensive list they can generate. Then fill all of them out, submit and hope for the best. It'll likely be a lot of cut/paste tedium, but if "they" are giving it away...since we're on the subject, what are other options other than the 529?
cash in the safe?
wealthy donor?
my daughter is doing the jc for transfer requirements then finish at either Cal State or UC.
Protip - because the 4 year colleges (at least out West) are going to be mostly online but with apparently similar tuition, junior colleges have lots more kids registering for the fall. If you haven't already gotten your kids registered and into fall classes you need to jump on it now.
