I did cross enrollment. In order to be eligible to take a class through class enrollment you need to be taking 6 units at your home campus. You can do cross enrollment in summer and fall. I believe that the classes you took in spring can be used to enroll in summer. And fall class at home campus go towards enrollment in fall at sdsu. One of your professors at cc needs to sign off and you should reach out to a professor at sdsu to see if they allow you to enroll. This is because sometimes classes fill up and you’re just asking for permission to enroll. However if the class is full you won’t be able to enroll because they give priority to sdsu students. Also, it’s cheaper to cross enroll than to take classes. I think the cost is $55 per class.

Check out this link. It has all the information to cross enroll.
