Galaxy High is an American animated series that premiered on September
13, 1986 on CBS and ran for 13 episodes until December 6, 1986.

But it was made by TMS, so I'll post to raam anyway.

The series opens with two American teens chosen from Earth
to attend "Galaxy High", a school on an asteroid (apparently
in the Sol system). One student is a jock (Doyle), and the
other is a bookworm (Aimee). The time is near future, and
the Earth does not appear to be of any importance to interstellar
society (which is non-human).
Upon arrival, Doyle immediately gets into a dominance battle
with cock-of-the-walk Beef Bonk (a giant rooster) and his Bonk
Bunch, whereas Aimee wins immediate social acceptance, gets
a makeover, and joins the cheerleading squad.

At this point, I have to wonder: why did these two apply to
Galaxy High? Both are motivated solely by the desire to fit
in and be popular, so why attend a school where profound
alienation is not only normal, but required?
In Doyle's case, he was clearly lied to: he's expecting hordes
of gorgeous alien babes to swarm all over him, all the time.
Aimee, apparently, came to be with Doyle, because she's
infatuated. Which means that they didn't want to attend
Galaxy High. So who chose them? And why? The series was
canceled after 13 episodes, so those questions are never
answered. However, the Founder's Day episode (11) does
tell us why the school was created - to produce transcultural
citizens. And by whom - a very wealthy man. (The principle of
the school has her own reasons - she was oppressed on her home
planet, and wants to help children develop gifts that are not
valued in their own society.) (Since Galaxy High is a business
venture, we might suppose that candidates with pre-existing
loyalties elsewhere are not considered, which excludes anyone
that society already recognizes as valuable.)
Since the objective of the school is to produce transcultural
citizens, it becomes reasonable that their first objective is
to imbue the students with balanced physical, mental, and
social skills that will allow them to be extremely adaptable.
In Doyle's case, that means crushing his over-inflated ego;
for Aimee, they have to build her up.

Peach-Moon Academy, from the anime Pani-Poni Dash,
features a school of misfits who are perfectly happy with
their state of alienation and who wouldn't have it any other
way - except for Kurumi, who is odd because she's the
normal one. (Actually, most of the students seem to be
cardboard cutouts - or at least, that's how the viewpoint
characters see them. And Kurumi has her own issues.)
In contrast, the students at Galaxy High are normal teenagers
in every way except appearance - and being extreme examples.
The gossip who never stops talking, the bubblehead with a
7 second memory, the reliable class president who's always
there to lend a hand or six (Milo de Venus needs his own
hentai doujin), the tart, the bully, etc. The main character
is definitely Doyle, with Aimee in a supporting role, and Beef
as the rival.

Next question: why are Doyle and Aimee arriving as transfer
students with classes already in session, and not at start of
classes?
Maybe the cabbie was delayed.
