<p>to OP: I did that last summer - just used assist.org and picked 2 classes. When done with the classes, I asked that my transcript be sent to UC Davis. I didn’t need to do anything else. It took about a month after fall semester started for my summer units to show up on my online transcript. The class names or grades didn’t show, just the units.
Also, your grades from CC do not count on your davis GPA.</p>
