Frequently Asked Questions

Yes, Khan Academy's core features—9,000+ video lessons, exercises, and progress tracking—are completely free with no ads. Khan Academy Plus ($12/month or $120/year as of 2025) adds offline viewing, removes watermarks, and enables parent/teacher features, but the free version is fully functional for self-directed learning.
