Subjects, topics, lessons, and segments

Each subject (for example, Local Anesthesia) is split into topics. Each topic has a few lessons, and each lesson is made of short segments, each one focused idea you can read in a few minutes.

• After a segment there's a short recall check.
• Each lesson ends with a lesson quiz.
• Each topic has a topic quiz that ties its lessons together.
• Each subject ends with a subject review quiz.

Importance stars show exam priority: ★ Less important, ★★ Important, ★★★ Essential. Use them to decide what to review first when time is short.
