"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 was a game changer for speaking practice too. I stopped trying to memorize perfect answers and just learned to sound more natural."
"The feedback on my essays and speaking was really helpful. It told me exactly what to fix, such as my organization and topic sentences."
