6 AP scores of 3 or above are basically 30 units (maybe a little less depending on what they are).
Take two summer courses at the CCC then you can apply in November and should be able to easily reach 60 semester by spring. Now, of course, it depends on how many required courses your major has which you can find on assist.org by entering CCC, UC and major. Many of your AP should fulfill IGETC. You will need the second English (comp/critical thinking). Two years of high school language in same subject fulfills the IGETC language.
You need to apply now to a CCC and take the English and math placement tests so you can quickly enroll in summer courses before they fill up.
The UCs like to see actual courses rather than a ton of AP, so two in summer and five in fall puts you in a good position.
Here’s how to calculate AP and gen ed. Some majors will let you apply AP to required courses as well. It should say on the top of the assist major page.
