URAP, but informally

<p>Okay, I'm sure not all undergraduate research is done through URAP. And that there are many Berkeley professors who will admit undergraduates but still didn't post their projects in the URAP site. If I contact a professor and he/she says that I can do research in his/her lab, is it possible for me to get URAP credits? I want some proof that I worked at a lab, and I thought URAP credits was a good way to prove this.</p>
