I’m not finished but will be by May 2018 and I want to start attending next fall 2018. Will they accept me and how long does it take?
Which college(s)? What other classes besides Math are you taking Spring semester?
UCLA, CSULA, CSUN, and UCI
Having all pre-req, GE’s and required major courses completed at application time will make you a more competitive applicant but finishing up a few requirements by Spring 2018, should be fine.
Here is the UC application dates and deadlines:

CSU applicatipn opens October 1, 2017. Depending upon campus if you are local, you could hear as early as January or as late as April.
Check each schools website in August for specifics.
Also check with your transfer advisor.
it depends - they are looking for you to have all the requirements done by May but, some may be required earlier. I would contact the schools directly and ask while you have time to rearrange your fall schedule.
