I had no high hopes for this show, and I was right, this show is awful. Let me start with the characters, we have: The smart fun girl(Chyna Parks); The crazy wacky Girl (Olive Doyle) ; And the Guy who hangs out with them (Fletcher Quimby) and has a crush on Chyna. Hasn't iCarly already done this? The characters are 2 dimensional, by that I mean they have no deep character what-so-ever. The acting is mediocre and sounds too forced and fake, making the show quite bad in general. Also, the premise is very simple and plain, I'm assuming the idea was: "Hey! How about we take middle-schoolers, and put them in High School! Genius!" The comedy is very dull and annoying, relying on randomness and visual gags. For example, Chyna opens her locker and a bunch of plastic balls fall out; Fletcher paints his teacher as a skeleton, etc. This show also uses young children in attempt to connect to the audience, which doesn't work.
Take my advice, watch something else.
