In my time studying close to a dozen APs, I’ve experienced the menagerie of awesome, decent, and waste-of-time resources. Over the past year, I’ve consolidated all the best resources and study methods I’ve gathered into one place: AcornPrep. Now, I’m excited to share what I believe is the most productive (and fun) way to get a 5. Locked in.

We literally just built the thing we wished existed. An AI tutor with infinite patience. Instant rubric feedback the second I submit my work. Real-time analytics so I can stop coping and know exactly what I need to improve on. And we’re making it free (or basically free) so u can stop chasing the huzz and start chasing 5’s.
