Here are a few tips to improve your TOEFL Writing score-Keep a standard essay structure in mind – Introduction, Problem Statement, Solution, Benefits of the solution, Drawbacks of the solution, Conclusion.
Dedicate each para to one heading, and understand that they do not necessarily have to be in this order. Write the entire essay first. Don’t listen to the critical side of your brain just now.
Once you’ve finished your first draft, you can always come back and edit.
