Aren't most things learned in School Worthless?

Now before you think I am immature for saying this, think, When do you use Algebra in Real Life? Most people aren't Physicists, How about needing to sort your Resume into Verbs, Nouns, and Adjectives? The most important things you need to know when Making a resume, is spelling correctly, Grammar, and Punctuation. History is important, I can admit, but What else? It seems about 90% of the Things I learn in an Average School day are Completely Worthless when I am Older.
