<p>I think the writing section is important. If the essay brings down your score thats understandable, but grammar is very important. Word on my computer doesnt catch all mistakes and if your writing an in-class essay, not matter how short, small grammar mistakes can make stupid you sound.
Or positive grammar can make you sound intelligent
Either way, when composing a persuasive work, it is important to sound like you know what you are talking about</p>
