Has anyone had experience with UC College Prep Open Access?

<p>In short, I came across this site that seemed to've had a vast array of high school courses (this including several AP courses). I emailed an employee of the University of California with concerning the curriculum that they offered and this is what I got in return: **"The open access content cannot meet the requirements of a full course experience led by a certified teacher and intended for academic credit but serves those who wish to study or review basic concepts. "</p>

<p>Should I just disregard this, treat it like a full credit course (my school offers credit by examination), and proceed with self-studying the course materials, how limited is the guest access to the site in comparison to full access, and are there other self studying sites that I could use? (preferably free)**</p>

<p>OH and if you're interested in doing the same thing that I'm doing, here's the site: UC</a> College Prep Open Access</p>
