@aleyna22 - yes. Often times the best writers are some of the worst at writing SAT Essay's (not to say you good SAT Essay Writers are bad writers). It's all about a formula: Intro - agree or disagree with the posed question.
Body 1 - STRONGEST example
Body 2 - SECOND Strongest example
Body 3 - THIRD Strongest example
Conclusion - 2-3 sentence restatement
The more you write the better!
