O Fallon High School Reviews

By a Current Student on

I would recommend anyone to move into the O'Fallon School district. They are almost finshed building the 9th grade center and new middle school. Many students who graduate go on to be very successful. It was a tad overcrowded when I attended the school, but I was kept focused.
