Tips for Best Results

Select Correct Essay Type

Argumentative essays are graded on thesis and evidence, narrative on storytelling and voice, research on citations and analysis. Selecting the wrong type causes misaligned rubric evaluation. Pick the type that fits your writing for the most accurate results.

Match Academic Level Correctly

High school expectations differ from graduate level with the essay grading tool. Rubric standards adjust based on the level you select — what earns an A in high school may score lower at graduate level. Setting the right level ensures you get fair, appropriately calibrated feedback.

Use Balanced Strictness First

Start with Balanced grading strictness with the AI essay grader. Lenient is too generous for improvement feedback, and Strict may discourage. Balanced provides realistic scoring that matches typical teacher standards. Adjust the strictness later once you know what kind of feedback works best for you.

Focus on Rubric Weaknesses

After grading, prioritize the lowest-scoring rubric categories from the AI essay grader. Improving your weakest areas yields the biggest grade increase. For example, if Organization scores low but Grammar scores high, focus your revision on structure rather than proofreading for maximum improvement.

Re-Grade After Revisions

Use the AI essay grader iteratively - grade, revise based on feedback, then re-grade to measure improvement. It provides consistent scoring across attempts, so you can track your progress over time. This iterative approach is the fastest path to raising the quality of your writing.

Save Feedback for Reference

Download essay grader PDF or copy rubric feedback for reference during revision. The justification and revision suggestions provide a clear roadmap for improvement. Keeping previous results helps you identify patterns in weaknesses across multiple pieces of writing.
