How accurate is AI grading?
AI grading is highly accurate for structured questions (MCQ, math). For open-ended answers, it provides meaningful feedback and scores, but we recommend parents review graded essays for the best learning outcome.
What data does Professor Turtle collect?
Only what's needed to make the app work — your answers and performance data are saved so you can go back and review your past work (up to the last 20 question sets). No data is sold or shared with third parties. No tracking or analytics scripts are used.
