About the AP-Equivalent Score (1–5)
Organic Chemistry 2 is taught at AP-equivalent depth. The score predictor blends 70% quiz performance and 30% topic mastery rate, then maps the result onto the same 1–5 scale used for AP Chemistry — so you can interpret your standing the way you would for any other AP science.
- • 5 — Top performance (≥ 85%): synthesis-ready, exam-confident.
- • 4 — Strong (≥ 70%): solid mechanisms; refine spectroscopy.
- • 3 — Passing (≥ 55%): foundational; rebuild carbonyl/aromatic chemistry.
- • 2 — Below passing (≥ 35%): focused remediation needed.
- • 1 — Beginning (< 35%): work through the lessons end-to-end.
