That brings us to our final recommendation to become a better writer - feedback. Ask for reviews of your writing, and listen to advice from teachers and peers. It's the best way to know your strengths and weaknesses.

All students have particular mistakes they make often. You'll receive repeated feedback about these areas. When you proofread, focus on them and cut frequent errors first.
Practice is vital to write well. Classwork isn't enough, so practice on your own. Develop a mindset for academic writing. That is, when you start to compose an essay, bring relevant techniques and useful language forms to the front of your mind. Know the points you want to make, use the skills you are confident with, and consider your audience.
