Hey,
I plan to transfer to UCLA, UC Berkeley, or another UC. I have one “W” on my community college transcript. When I transfer to a UC, will my new UC transcript show the “W” that was on my community college transcript? Or will the W be purged off?
The W will show but they don’t care. Don’t worry. 
I don’t believe your new UC transcript will show your grades from a previous institution. When you apply to graduate programs, you will have to send a transcript from each institution that you attended.
^^^ he’s correct. I misunderstood. They see the W from your CCC transcript but the UC side of things starts over at ground zero, so no grades or GPA from the CCC are calculated.
