Talk to your high school counselor or your college adviser. They can give you some essay examples and you can have them proofread your essay once you are done writing it these professionals will have insight into what the admissions officers are looking for in an essay. And it is always a good idea to have one or two people read over your finished essay in order to make sure there are no grammatical errors.
Essay assistance is exactly the type of coursework help which students at all levels can benefit from. There is no question of such essay assistance infringing any academic codes of conduct.
