high IQ people perform poorly when they are in an environment that doesn't challenge them the right
Sometimes it's not even about the challenge, but about an environment actually punishing you for doing a smart thing. (Or for doing a thing that seems smart on your level, such as publicly correcting your teacher's mistake. Yeah, it's obvious to us why this is probably a bad idea, but not to a 10-years old child. The child does it, receives some kind of punishment, and most likely learns the wrong lesson that it is wrong to analyze too much what higher-status people are telling you.)
If the lack of challenge were the only problem, we could fix it rather easily by adding more difficult alternatives within the system. For example if a child is bored during the math lessons, you could just give them an option to take the final exam at the beginning or in the middle of the year, and if they pass, they don't have to attend the lessons (they might have to stay at school, but be able to read something, debate with other similar students, or do some private project on the computer).

I just got a new appreciation for my country's school system from the fact that this probably being a bad idea wouldn't even have occurred to me without you mentioning it. When I was 10 - or for that matter any age - and disagreed with my teachers, they'd just look up the right answer in some authoritative reference and admit to being wrong if necessary. I thought this was the norm everywhere.
A brief essay intended for high school students: any thoughts?
If you go to school, take the classes that people tell you to, do your homework, and engage in the extracurricular activities that your peers do, you'll be setting yourself up for an "okay" life. But you can do better than that.
The school system wasn't designed to help you achieve your goals. It wasn't designed to optimize student welfare in general: it was cobbled together by many different actors with many different goals, from politicians to teachers to parents to colleges. It often suffers from inadequate resources. Even if the school system were optimized on average, the one-size-fits-all approach it takes means that it wouldn't be optimized for people who differ in any relevant respect from average. Compared with what you can achieve by carefully thinking about what your goals are and how you can achieve them, following "the system" fares poorly.
By putting you in this situation, society has fouled you. Yes, as you suspect, a lot of the stuff you learn in your classes is crap. And yes, as you suspect, the college admissions process is largely a charade. But like many fouls, this one was unintentional. So just keep playing. Rebellion is almost as stupid as obedience. In either case you let yourself be defined by what they tell you to do. The best plan, I think, is to step onto an orthogonal vector. Don't just do what they tell you, and don't just refuse to. Instead treat school as a day job. As day jobs go, it's pretty sweet. You're done at 3 o'clock, and you can even work on your own stuff while you're there. — Paul Graham in What You'll Wish You'd Known
Some subjects are more important than others
High school can give an illusion of democracy between the different subjects you study: they all seem to get equal weight in class time and in grades, so you may believe that all subjects are equally important to study. This is not true even in general: some subjects are more important to study overall, and within each subject, some topics may be more important than what school seems to suggest.
Because the method of exposition and choice of topics in school is likely suboptimal, it generally makes sense to learn the important topics well ahead of time, and deal with the others as needed to do well on the courses.
It's important to choose your extracurriculars well
Many common extra-curricular activities (in particular, many school clubs) are not the most productive uses of time. If you go with the flow and sign up for the activities that the people around you are signing up for, you may sacrifice the opportunity to develop yourself and accomplish far more.
Consider alternatives to high school
Consider homeschooling and online school. Depending on your situation, these may be superior alternatives to regular high school for you.
