When you’re getting ready to take the SAT®, the ACT, or another standardized test, the stakes are high (as you know). Portions of standardized tests are black and white. You either choose the correct answer, or you don’t. Writing is different. There are a multitude of factors that come into play when writing is being graded.

On those tests, you need clear organization. You need to use evidence and analysis to build a clear argument. It can feel nerve-wracking to know that someone you haven’t met will be grading your work.

To make sure your nerves don’t get the best of you the answer is simple: PRACTICE WRITING!! One solutions is to use technology. A writing software tool is a low stress, high return way for you to sharpen your writing skills with an impartial reader.

Technology will give you the benefit of fast, data-driven feedback - meaning you can write and write and write and write, getting feedback the entire time. It sounds tedious, but test prep is important and worth the effort.

Good luck!
