School Reviews
5 12/3/2008
Let me tell you the truth about Ygnacio Valley High School. I've been a student for 3 years, and I must say YV is truly an incredible school. I get scorned by people from other schools when I tell them that I go to YV, and I think it's humorous that people can judge a school's potential by listening to rumors. Yes, the majority of the school (racial diversity aside) isn't up to par with state standards, but that has nothing with the school's educational aptitude. Spectators observe YV and only notice the negatives. What's overlooked are our true diamonds in the rough: our top scholars, our excellent honors/AP programs, our diverse selection of courses, and our hardworking teachers who strive to students succeed. Do you really think Ygnacio Valley High is an easy school? Try taking our Honors Chemistry class, or our AP US History, then come talk to us.
