I am a student from Aragon High, teachers are unfriendly and unwilling to teach well. Classes are overpopulated (over 35 students) I suggest a smaller school where the learning environment will help students concentrate more.

This school has too little fund for such a large population. Classes are overflowing and students are out of control. I may suggest a private school to other children going to high school.

Aragon is a great school.A large public high school in a San Francisco suburb, aragon is a national top rated high school ( Newsweek), offering great academics, excellent extra curriculars, support for a diverse student body, and a culture that challenges students without an intensely stressful culture. Every year students get into Stanford, UC Berkeley, UCLA, USC, etc, but there are also a large number of students whose goal is community college, and the school supports all of them. Great music program, many AP classes, excellent motivated teachers, a friendly safe supportive atmosphere.

When I was there from 1968 to 71 it was a great school they had a real good aerospace program. Don''t know if they still have it. Anyway it helped me get a job at United air lines where I worked my way up from doing cargo to working on the planes where I made big dollars. I did have to go to CSM also for a couple of years but it paid off. I worked with some of the best people at United. To bad many are gone now retired like me and the new people have taken over and you see the results. Greed and could care less about the passengers and the service. We used to treat people like human beings not cattle. And I am sure that the school has also changed for the worse also.. Oh the school had real good drivers ed class that had new cars where I learned to drive. I gave the school 5 stars for back in the day.. Not sure about now. The teachers then were the best. I know many have passed away. Sad about that. I am sure the teachers don''t make enough money to live on now. The houses around there are starting at 1.5 million plus. And your Taxed to death. I left California when I retired. San Mateo used to be a great place to live.
