"I'd tried two other prep courses and failed. The adaptive engine on QuantegyAI actually figured out I was weak on Functions — I didn't even know. Passed with a 174."
"The 1-on-1 session with Dr. Mienie was worth it alone. She walked me through three Calculus concepts in 30 minutes that I'd been stuck on for weeks."
