My Life as Liz

I think it is loosely scripted - It is based on her senior year of high school and I believe the main cast (and that mean girl) are considered "realityTV actors," - of course these are my assumptions, I can't seem to get a clear answer - whatever it is I'm enjoying it so far.
 
^ there's an implication that she just didn't want to fit into how she "should" be as part of that crowd, and she had different interests that they didn't accept. I think she realized how mean they were to others and decided she wanted no part of it... then she found her nerdier guy friends who accept her for who she is.
 
so.....is this basically suppose to be a scripted show made to look like it's a reality show?
i'm confused. kinda like the office?
but i do enjoy the show!
