"The AI grading on my APUSH DBQ is actually useful. Goes criterion by criterion and tells me exactly where I lost points."
"Went from a 1140 to a 1290 in 6 weeks. The daily drills and wrong-answer explanations are what did it."
"My calc class uses the game mode on Fridays. It's actually the reason some of us study during the week."
We don’t charge for tests, AI explanations, or score reports - and we never will. Every dollar from a donor pays for AI grading, hosting, and one more month of free prep for a kid whose family can’t spend $1,500 on a tutor.
Thank you to the donors keeping this open for everyone.
