Professor Turtle acts as a personal AI tutor that generates curriculum-aligned questions and grades your open-ended answers with detailed feedback. Instead of doing dry multiple-choice questions, students practice structuring full explanations, helping them prepare for real school exams.
Quotas are in place to ensure resource availability and prevent misuse of advanced AI model endpoints.
Your Pro weekly allowance (80 sets of questions and markings) is refreshed automatically every Monday at 00:00. This resets a clean slate for the week.
