This school is super!!! All three of my children attended SMMS and received an excellent education. If you want a highly academic school, then this is a good one. The curriculum is rigorous but all the teachers are very supportive and stay every day after school for free tutoring. The kids enjoyed all the activities offered. The principal is nice and does not put up with bullying. It's a strict school which I liked. They have rules and expect the students to abide by them.
