10/10GreatSchools RatingParent Rating AverageOverall, I’d give Redwood High School 4 out of 5 stars. The school has a pretty competitive environment — a lot of students really push themselves to get the best grades, which can be motivating but also very stressful at times. Some kids can be a bit mean, and I did have a few teachers who weren’t the nicest.That said, most of the teachers were genuinely kind, supportive, and passionate about what they teach. They helped me rediscover my love for learning and actually made me excited to come to school again. Despite a few negative experiences, the good definitely outweighed the bad.Other Review8mo ago - Anthony G. Bacich Elementary School
