Hello, I added commas where need and also changed some words so you might want to look over it again to see if it okay for you and I would like you to know it's a bit wordiness, so I recommend to improve readability, consider breaking this into multiple sentences.
I had a rough sophomore year, but they helped me with my
grades and brought them back up and this year( junior
year) has been perfect, but for both years there weren't
many fun activities our school is too underfunded, and
most money we get goes to the middle school last year we
had a Halloween dance, prom,and we had dominion of
terror that's all we had for activities this year we have no
Halloween dance, No rule of terror and most likely from
what I've heard...no prom but I see all these other
Sheboygan area schools having dances football games and
all this other stuff, but we can't even get a single dance,I
understand that we are in school for education but we are
also here for a great high school experience before have to
be pushed into the adult world and never have anything
like this again but overall there teachers and education
system is excellent but we are really underfunded and don't
get a full high school experience.
