The main advantage of attending a public school is that you get much less competition and stress than attending a private school. However, the drawbacks are that a public school generally has a lower standard of education than a private school's. While that seems like a vital disadvantage compared to the private school, I think that having a lower standard of education than a private school's might be for the better. With a lower standard of education than a private school's, public school students will have to work harder to succeed, which builds perseverance and determination. These two traits are, in my opinion, essential to a successful and secure future.
The advantages of attending a private school is that private schools have a better level of education, and more intelligent,diligent students than a public school. However, that might lead to a disadvantage as students might transform to be lazy and uncooperative. The disadvantages of a private school is that since there is so much competition among students, attending a private school might result in illness, suicide, or other sorts of physical and mental harm.
In conclusion, since there are much more and vital evidence that support going to a public school rather than going to a private school, both parents and students can be assured that going to a public school is the better solution for a better future.
