I am a current student at Aberdeen High. I for one love this sckool. M teachers actually teach us things we will need to know in life, important life lessons. I told one of my teachers i didn't need to learn something to become what i what to acheive. He gave me a real life situation of someone he knows to apply that knowledge. I am a very proud student. there will always be the normal high school drama, but some of us learn to cope and handle that with the help of ours teachers. when an important event happens, we discuss it in school to help ourselves if or when it happens to us. i am very happy in tis school with my teachers and administaters, thank you.
