I went to my mother for advice on high school. This is what I got from her little lecture:

    The first piece of advice that I believe will be the most helpful is to turn in your paperwork on time, or have it done early if possible.   Make sure that you get it turned in on time to get the maximum number of points.   And also make sure that you have a separate folder and notebook for EVERY class.   I have found this to be most helpful.   In high school, it can be easy to get your papers mixed up because many of teachers give you homework everyday. If you really have to use another notebook to write something down, tear that piece of paper out and stick it in the folder for that class.
   The second piece of advice is to take the time to study the information that the teachers give to you.   Study for tests and quizzes several days before the exam, especially for semester tests.   Some teachers make that grade worth one-third of your semester grade, and if you really want to get a good grade and do well in school, you need to study all of the time. If you are stuck on a problem or idea and don't understand it, don't be afraid to ask the teacher for help or a friend who is smart.   It always pays off to ask for that extra help if you don't get something.
   The third tip is to not skip class because you don't want to go or because you don't have your homework finished.   If the teacher, someone that is looking at you suspiciously or the principal catches you, you know that you are going to get caught.   You will have to pay the consequences for skipping class. To add something else, you might miss a class discussion, or you might miss the homework assignment the teacher would be assigning for the class work for today.
   High school may be tough, but it can be beaten.

"School in a Perfect World"

   If I could choose what school would be like, it'd definitely be different. Lets start with the rules. Phones would be allowed. Period. The no phone rule is a tad ridiculous. I am aware that they van be distracting, but if it's the lunch hour and break, why the heck not be able to use them? There's no harm in texting and going on the websites we choose. We pay a lot for our phones and we can't use them seven hours out of our day? That seems rather obnoxious. As well as the fact that teachers think it's okay to take them away from the student. If they can take away our personal things, we should be able to just take theirs. So people think it's okay that they take it away because they're older and can read from a textbook? Doesn't sound too fair to me.

   Now, on to the hours. If the teachers think it's necessary to keep students locked in a school for seven hours straight, we have a problem. It shouldn't take that long of time to teach a few subjects. I'm not trying to be rude, just stating what I think. People have lives and school is stressful. Maybe 10am-2:30pm would be more rational. It's have enough time to learn everything we need to and still have a life. 

   Lastly, lets get more serious here; no more bullying. Each day an estimated 160,000 students in the USA refuse to go to school because they dread the physical and verbal aggression of their peers. Many more attend school in a chronic state of anxiety and depression. Bullying can result in reluctance to go to school and truancy, headaches and stomach pains, reduced appetite, shame, anxiety, irritability, aggression and depression. Bullying is a direct attack on a student’s status, sense of belonging and core identity, and often results in low self-esteem. The effects of bullying often continue many years into adulthood. In the most extreme cases, targets have taken out their anger and despair through school shootings or by committing suicide. Now you try to tell me that school making you want to kill yourself is normal. 

  I  believe... there's always going to be a choice. Even if both choices are bad ones, there's always an alternative. Not always are the decisions going to be easy, but no matter what, you have the right to pick. For an example, you can choose to go with the flow or be unique. Sadly, being unique doesn't have much meaning anymore. Saying everyone's unique is like saying everyone's the same. Anyway, another example would be choosing to be positive and uplifting or bringing everyone down to your level. You have the choice to reflect who you are through your actions.
  On a more deeper level, you have decisions that come from within. You have the power to choose your own happiness. If you want to forget about the judgement and push away people's negative attitude, you can. If you think you can't achieve happiness, you're probably right. You have to have the strength to believe you're worth it. If you don't, you're practically not letting yourself. If you had to decide between settling with life or living it, what would you pick?
  Some people can't see their choices. They might think the only way to deal with the stress in their life is drugs or alcohol. If you think that, then that's your way of living. I'm not saying it's bad or putting that lifestyle down, I'm just making a point. Some things you can't choose; like your height or your family. You can decide how to deal with those things, though.
