CE modules and certificates
The /practice landing, three V1 modules, certificate issuance, and the public verification URL.
Continuing education modules bundle the standalone play exercises into structured sequences with a per-exercise score threshold, a credit-hours value, and a shareable certificate at the end. The landing page lives at /practice.

The three V1 modules
NSAID foundations (1.5 hours)
Two textbook NSAID retrosyntheses (aspirin, acetaminophen) plus a flaw-spot on a poorly-conditioned aspirin route. A solid warm-up for analgesic chemistry and a low-friction first module to assign to a class.
Industrial process bridge (2.0 hours)
Steps from textbook to plant-relevant chemistry. Bridges ibuprofen build-from-disconnect with a fabricated-step diagnostic and a walk through the model on acetaminophen. Aimed at the continuing-ed audience; assumes students are comfortable identifying disconnections.
Aromatic substitution, deep dive (1.0 hour)
Two aspirin disconnections paired with a masked-retron variant. Reinforces aromatic acylation reasoning under different exercise modalities. The shortest module; useful as a recap or refresher.
How completion works
Each module has a list of required exercises and a minimum score per exercise (typically 70-80 percent). Take an exercise as many times as you need; only your best attempt counts. Once every required exercise clears its threshold, the module becomes eligible for certificate issuance.
Certificates and verification
Click Issue certificate on a completed module. The platform mints
a PDF (your name, the module title, the credit hours, the date of
issuance) and assigns it a public slug. The certificate is viewable at
/practice/certificates; the public verification URL is
/verify-cert/{slug} and is safe to share with employers, licensing
boards, or LinkedIn. The verify page renders the module title and
issue date without exposing any private account data.
