how can i write a good essay ?
my essay is about writing a letter to my head teacher about changing the uniform thanks

good essay is about having good arguments ( lists of clear reasons) and evidence ( proof )

if the reason you want to change uniforms is because they are simply ugly, you must create a better reason — because that is not a good argument

Our school must value the beliefs and desires of the student body. In a school in which students feel valued and trusted, the self concept of the student body will improve. When the self- concept and self esteem of individual students are improved, the individual student will feel happy and will do better school work and be more involved in the student community.
