The Writing portion of the ACT measures your writing skills—specifically those writing skills emphasized in high school English classes and in entry-level college composition courses.
Strategy #1: Stick to what the prompt is asking with this portion of the ACT. Be sure you understand the prompt and remember not to get off topic with irrelevant information.
Strategy #2: Take a clear position on the issue. Make sure your introduction lets the ACT readers know you understand what the prompt is asking.
Strategy #3: When writing under the time constraints of the ACT, it's all too common to make mistakes. Carefully edit your work to correct the common mechanical or grammatical mistakes.
Strategy #4: Impress the ACT representatives by throwing in facts or statistics to help backup your point of view.
Strategy #5: Create an outline to be sure your essay flows. Use the outline as a reference to double check the organizational structure.
