What? Seriously?! No no. That's amazingly far from the truth. Math, surprisingly enough, actually makes sense. The reason a lot of people do badly in math is because they stare at new concepts telling themselves "This doesn't make sense" over and over instead of trying to make sense out of it. If you want math to be easier on you, remember to tell yourself "This DOES make sense, I just have to find the sense in it." Seriously, treat math as a puzzle game. Learn the rules of the game and it'll be easier. In fact, since math is all about finding patterns and logic, human brains, once they "get it" tend to want to do more math because your brain is designed to make you feel pleasure when you find patterns and follow logic.
Now that that's out of the way, what I hated about school is how they make you learn so many useless things. Learning the elements of the periodic table? Ha! They actually give me a copy of the periodic table in college whenever I need it. English as a second language? (English is not my first language) They taught me the exact same things for years and I ended up learning more by watching TV. Biology? Yeah, that changes so much that I'm now learning that everything I learned in school about it was wrong.
And here's my favorite. Math? If you are not going to be a scientist, engineer, or computer programmer, you don't need to learn anything beyond pre-algebra or even just basic adding, subtracting, multiplying, and division. Seriously, they just want you to learn math just in case you choose a high-end math career later, but even then you didn't have to spend years in school learning it because if you need it, they'll just re-teach it to you in college. Assuming you are not a high-end math student, they somehow still want you to math while studying.
My other problem with school is teachers that don't know how to teach. I've had enough teachers who put stuffs on the wall, explain it, then go and do the opposite, get lost in their explanation, and then blame the students for not being smart enough. I'd say the worse was my first gym teacher. He refused to teach sports to a lot of students because they weren't good a it, but how were they supposed to be good at it if he refuses to teach?
For all of those still in school, hang in there. Sure, it can be a pain, but later on, even if you don't need whatever they teach you, you do need your diploma and such to find a good career. You'll be happy you got it over with later, especially if you get a good job.
If you can't tell by all this rant, I'm probably going to be a teacher.
