I didn’t apply to most csu like I should have. Can I apple for the winter term (starting January)? How does that work? And will I be offered housing?
There are very few CSU’s that allow Winter/Spring admissions.
Go to CSUMentor.com for application details, dates and deadlines.
From looking at the site, the application period for Winter/Spring 2018 are not yet open.
I would guess that the current Fall 2017 cycle will need to close first (after June 1 to allow for transfer admission) so that they have a good idea as to how many students (if any) can be accommodated off-cycle.
In the meanwhile, here is a list of schools that still have enrollment open for Fall 2017:
CSU Monterey Bay
CSU Channel Islands
CSU Dominguez Hills
CSU Maritime
CSU Los Angeles
