Basicly, school is quite needed. But they just learn kids so many stuff thats totally obvious already. "How to have sex and why" as a chapter in the second grade was one of them. Its gross to see all those images, and its already dang obvious how and why, since your parents probably already told you about it 5 years ago. French, something I never needed in life. Drawing, which is fun, but also not needed. Music, also not needed. This is what you would all think, right? Wrong. Although it might not be usefull to you, it is to others.
But....that still means its not usefull to you. And thats why I think you need to be able to choose from an earlier age what you want to do. All the knowledge from "useless"(which means to you) French lessons will definitly hinder you from doing important ones. If you get horrible grades on it, your chance of failing will be bigger. So you're forced to learn it. And by doing so you'll waste time that could have been spent on important lessons, and/or free time. (Oh yes, before you think free time means laziness, its not nessesarily that. You'll learn alot from information sources like people around you, TV, internet, and more. It helps you with general knowledge.)
So, basicly we need are more and earlier choices, and school should stop pointing out such obvious things. Its irritating to have french for 2 years, and only being able to stop it after that.
