Courses & Lessons

Courses are structured as ordered sections containing sequential lessons. Each lesson can be a video stream, PDF document, rich-text content, auto-graded quiz, or external link. Learners progress through lessons in sequence with completion gating per lesson type.

Video

Document

PDF document lessons rendered inline via the Calisto PDF viewer. Timer-based completion tracking for read-time verification.

Text

Rich-text content lessons stored as structured content. Inline formatting with headings, lists, and embedded media references.

Quiz

Standalone quiz lessons with auto-graded questions. Three question types: multiple choice, true/false, and short answer. Configurable pass threshold.

Link

The Certification Engine

Three question types. Auto-graded. Certificate on pass.

Multiple choice, true/false, and short answer. In-lesson quizzes gate lesson completion. Final exams gate course certification. Auto-grading with scored results. PDF certificate generated immediately on pass.

Quizzes & Certification

Three question types. Auto-graded. Certificate on pass.

In-lesson quizzes and course-level final exams use the same three question types with auto-grading. Passing a final exam triggers immediate PDF certificate generation with public verification. Quiz attempts are tracked per enrollment with configurable retry limits.

Multiple Choice

Select one correct answer from a set of options. Options stored as JSON array. Auto-graded against the correct answer key.

True / False

Binary choice question. Auto-graded. Used for factual recall and comprehension checks within lessons and final exams.

Short Answer

Free-text response graded against expected answer. Supports exact-match and partial-match grading depending on question configuration.
