Golden State Teacher Grant: 20k seems too good to be true?

I'm in the process of enrolling in an on-line based math credential program. It's not cheap. In fact, it's about 20k. Has anyone received close to the full amount?

Unlike with other grants, I was told it wouldn't appear on the university financial aid portal. I'd just be mailed a check based on my award amount and I can choose to pay off the loans I'll be taking out with it.

It all just seems a bit overwhelming, so I wanted to know if anyone has any direct experience receiving it.
