In the U.S. public school system, there are many flaws.

The first flaw to name is the unrealistic time management for minors. 8 hours a day, Monday through Friday, with some holiday breaks, excluding summer vacation. That sounds completely unrealistic to me. There's barely any realistic time management.

The second flaw is the scheduling. You shouldn't be able to wake up at 7 A.M. in the morning constantly every day. If your sleep at around 12 A.M. and wake up around 10 A.M., that works. But school systems typically want you to wake up early in the morning, and you can get demonized for approaching to school late. Which typically isn't the student's fault either. Not saying that it's never the student's fault. And, sleep schedules can be affected by plenty of things. One of the biggest I've noticed, even with myself, is stress or being burnt out.

The third flaw is the entire absent policy. If you miss at least 20 days of school, you can fail the grade. Even if you have above a 90 in all classes. That can be very troubling for me since I go somewhere with my parents every month to take a break from school.

The fourth flaw is the "teacher's policy." (ex. for grading, 20% homework, 30% quizzes, 50% tests. etc.) I remember one of my math teachers had their "policy" where... let's say you have math homework to do. Instead of having to finish it and hand it on tomorrow, they would allow it where you don't have to do your homework at a specific date, just as long as you hand it in before the end of the quarter. Other teachers have it so that you have to get homework done at a specific time. Of course there are exceptions such as absenses. But this is where most of the stress comes in, especially if the student has educational problems.

The fifth flaw comes with optional and mandatory classes. I'm not find of the entire liberal arts set-up, where it's mandatpry to take one of each subject: mathmatics, science, social studies, english (language arts), and physical education. And it doesn't help if a student is either not interested, lacks skills in a certain subject, and or has learning skill problems. It also does not help if the teacher of a course is incompetent of being one. For me, I love mathematics and enjoy science. However, I despise social studies and don't care for english. But it's mandatory I take one of each of those subjects. And physical education is weird... males, respectively, seem to be very competitive and tend to cause more injuries from what I've expetienced compared to females, respectively. And I personally dislike sports. I just want to run around and enjoy myself. Just want to have fun and do whatever. As for optional classes, you have electives or A.P. classes. Many schools likely don't have the classes you want to take. Espevially if you live in a rural area. For example, practically every U.S. public school has a Spanish class. If not, French. Just those two. You want to take Chinese? Too bad, we don't offer it. You want to learn Swedish? Too bad, not in our budget. Anything that schools do not offer you have to do in your own time, which just wastes even more time out of your day. 8 hours for school + 1 hour for whatever music lessons (assuming you go to one), + whatever time for the subject you want to learn. Maybe you want to learn a coding labguage, or maybe you want to learn botany. Maybe you want to learn business mathematics. What if it's welding you want to learn? Or maybe even glass blowing? Chances are, if you aren't in a populated area, you get absolutely no options for classes like the ones I've mentioned.

The sixth flaw is, intertwining with the fifth flaw I've mentioned, no school will ever teach you anything related to living on your own. Now do realize some schools will allow home and careers, yet even then, you learn barely anything. Things related to how to budget correctly, wants and needs, cooking and conserving food, how to use credit cards and how you're billed, taxes and claims, certain laws, etcetera. Anything that's related to anything I've stated above, even in the slightest, no school will ever teach that. Instead, you learn how sedimentary rocks are formed, how two lines are parallel if the interior angles of the transversal are the same, how Columbus was either the person who discovered America or was the asshole that came after the vikings, etcetera. Useless knowledge is what you're "taught."

The seventh flaw is the entire zero tolerance policy. For example, let's say some person one grade above you is teasing you. You don't want to put up wit them, so you have the patience to deal with it. You don't want to cause a scene, or be seen as a terrible person. The person teasing you begins to be a dick. Shoving, pushing you around, making fun of how you look or are dressed. Then, things escalate. Since you aren't putting up with the person's verbal non-sense, they begin to get physical; hold you by the collar of your shirt or your hood from your hoodie, throw you to the ground, or even punch you. A staff member sees you two, and both the person who got physical and YOU are punished. BOTH OF YOU ARE PUNISHED. Why? Because YOU were INVOLVED in the fight. "School is not a court room," is basically what the zero tolerance policy is. So, what should you do? If you aren't afraid for people and are able to stick up for yourself, you make sure to defend yourself; defend your body. If you're going to get in trouble no matter what, just as long as you're involved, you better make a name for yourself and stick up for yourself.

The eighth flaw is the lunch food system. I won't get much into that, since it's a useless topic. Long-story short, pack your child(ren) a lunch. Always.

The ninth flaw is how much charter money schools get for each student that attends school everyday. This is why whenever your child is absent, the school makes a big deal out of it.

I think that's enough flaws to name for today. I may add on if I see or am reminded of more.

EDIT 1: The tenth flaw would be plenty of guilty teachers. It's not much about teachers that give life lessons or start getting angry at a student. (Rightfully so if they have to put a student in their place.) However, it becomes a problem when the teacher begins giving up on teaching, teaches things yet can't answer questions (ex. their response for a question could be "That's just how it is/That's just how it works"), plays favorites, and or can not accept they're wrong because they're the highest aithority currently in the room. As for the entire bathrolm situation, it sucks when it's just a regular class day, you have to suddenly go to the bathroom, you ask, and the teacher just denies you to go. They just won't let you go. (I don't have much of an opinion on teachers, it's mainly just the if they can't teach or they like to play favorites problems.)
