School Reviews
2 10/10/2025
I hated it there. Absolutely no support in furthering my musical interests. You had to already be good at something in order to get attention. Too much overemphasis on sports and competition, not enough emphasis on understanding individual needs. Fads were shoved down our throats. MAJOR bullying problems. Some of the teachers made it worthwhile, but like any high school, the only reason WWSHS gets such good ratings is because of high-ranking test scores and an unrivaled football team.
