Are these courses graduate level?

[videogamesrock]

So I'm considering taking a few courses at UCLA Extension in Taxation. I'd like your opinion, since the courses are all but one, x400 to x499, would they be treated as graduate level courses?


X 400 to X 499: Generally post-baccalaureate credit-bearing courses and lecture series in professional fields; designed in content, focus, and presentation style to standards of instruction used in degree programs. Credit earned in these courses may lead to the award of formal certificates by UCLA Extension, and may be transferable for advanced standing in degree programs in professional studies elsewhere, subject to the procedures of the receiving institution.
