Writing improves through constant evaluation and feedback. For TOEFL, attempt a few integrated and independent tasks, then review your performance with a TOEFL practice test to compare how your responses measure against sample high-scoring answers. For IELTS, run your writing tasks through an IELTS essay checker to analyze coherence, task response, grammar range, and vocabulary use. Together, these tools help you notice patterns in your mistakes and gradually develop strong writing habits.
