School Reviews

  • Recommended July 27, 2013 - This school is the most amazing school in Texas, and one of the best in the entire United States. Look into the statistics on student performance and you will be amazed: average SAT around 2100, average student score of 4.5 on an average of 8 AP tests, 50% or more National Merit commendations per year. These numbers are crazily impressive. Also, the school is close to 60% non Anglo.The school has a reputation for being a math science school. It is great in these subjects, but also in every other subject, including visual and performing arts and foreign languages. You have to visit to understand all that happens there, and to experience the culture that embraces learning more than anything else. - Posted by Parent
