# Lesson 1 complete; primaries deferred

Learner finished lesson 1 (when service workers fit) with all quiz answers correct. Can place SW vs dedicated worker vs Cache Storage alone vs CDN/HTTP cache in design-review style decisions. External primaries (web.dev Learn PWA · Service workers; lifecycle deep dive) were **not** read this session. Next lessons should teach registration and the first install → activate path from cited sources and use Jake Archibald’s lifecycle article as the deferred primary — do not re-teach the full spectrum from zero.
