The pictures are nice and clean... but the animation part feels a bit boring and awkward. For example... When the characters are moving and shifting around they have little to no physical feedback on the gravity and force that is affecting them.
During the cartoon, there are some moment where it is unusually silent. The classroom can have a background noise as if there were more than the number of drawn characters.
The jokes are pretty basic and could have been funnier to have the jokes animated into their own scenes as in "shorts" form. It doesn't feel natural to try to have the jokes crammed into one skit.
Beside these down points, the cartoon is pretty solid, but could have been constructed better.
