Important in school. I do think everyone should know the basics in MATH for life, but I don't think knowing science will ever really help me for what i want to be when i'm older. And finding X will never help me either, but still important for school and in some jobs very important.
I dislike math very much, but that's only because I messed up and now I'm paying for it :/ . Science is ok. And although there not my favorite, it's used daily all around the earth. Math is most important though, you have to learn how to do your tax, count your bills, etc. so you don't get cheated on..
