Preparing for USNCO 2026?
Choose the path that fits you best:
1. Take Live Lessons with Dr. Chen – weekly class from late Aug to early Apr
- Taking AP Chemistry in the fall --> Level 2
- Completed AP Chemistry --> Level 3
- Aiming for Winning National --> Level 4
- Not sure which Level? --> take the diagnostic test
2. Prefer to begin right away? – Self-paced
Purchase recordings and class materials for Level 2, 3, or 4 and Summer Organic Chemistry in 2024-25 and start learning at your own pace!
