school is new, it is the experience period of your life that you will never forget. Like primary school you also have a memorable time, but you would be too young and not know how to enjoy the relationships between friends. Also you would probably forget a lot for you were very young. The day I started high school I felt like never again, but once the first day is over you will feel released the next day.
High school: It is mostly about the middle educational system. People find new friends in different activities and different personalities. But also you might have to risk the idea of being judged. As always people can be judgementative when they grew older and knew better. More things are likely to happen when the teachers are not supervising them which is most of the time. If you are one of those that cares depths about what character you are than it might not be a great idea to do that. Also it is a life experience, in a educational and how you enjoy spending time with your friends.
Primary school: Is about the basic learning for primary students that might have just had the first opportunity to get an education. It teaches you the basic learning of English, Math and some physical exercises. More than that you can also make your first and ever made best friends apart from kinder where you would probably be non memorable because of your age. Where as primary school they teach you stuff like simple and daily words and some basic math skills to get ready for high school.
University: This part of our educational journey is about the academy school that installs your future career ambition and how to get on. It is not like primary and secondary, this part is about the career and the study you are facing, the school of institution you can call it. It does not teaches you math and English or french or physical exercises. It teaches you the things you want to learn. Like if you are more of a artistic person rather than a sporty person than you can choose to refuse to learn sport because they believe you are well enough to decide, the learning and the action you are going to take towards your determination. But also not everyone can go to uni. some people just finishes high school and started working. That is perfectly normal, you still can get wages and salaries but you will not be as professional as your colleagues. Because they would have finished university and you would have only finished high school.
