"I went from 81 to 106 in two months. The AI grading was honestly great. It pointed out things I didn't even realize I was doing wrong. Petra really helped with my speaking too. I stopped trying to memorize perfect answers and just learned to sound more natural."
"Having unlimited practice made such a difference. It showed me exactly what I was doing wrong and how to fix it. I felt so much more confident on test day. I wish I'd gotten it sooner."
"Speaking was always my weakest section. I practiced so many questions and finally broke through. The unlimited practice really helped."

How accurate is the AI grading?
Our AI is trained on official ETS scoring rubrics and calibrated against thousands of scored TOEFL responses. It provides consistent, detailed feedback that closely mirrors human raters. While PrepEx gives you excellent practice and feedback, remember that only official ETS tests count for university applications.
