Please read Writeacher's post to All Students.
Using HELP in your subject line doesn't give us a clue about what you need.
As Writeacher said, please use a specific subject heading -- like MATH, ENGLISH GRAMMAR, PHYSICS.
An even better subject heading would be more specific -- like -- FACTORING, SHAKESPEARE, PRONOUNS, CIVIL WAR.
The more information you can post, the better and faster we can answer your question.
