Quizzes

Overview

This directory is the quiz hub for the Zero-to-AI course. It does not yet contain quizzes for every phase.

Use this folder as a growing assessment library while the wider quiz system is being built out. Quizzes help learners:

• Assess prior knowledge before starting a phase (pre-quiz)
• Validate learning outcomes after completing a phase (post-quiz)
• Identify knowledge gaps for focused review
• Track progress throughout the course

Quiz Format

Each quiz contains:

• 10 questions (mix of multiple choice and code-based)
• Time limit: 15-20 minutes
• Passing score: 70% (7/10 correct)
• Immediate feedback with explanations

Available Quizzes

Planned Coverage

The long-term goal is phase-level pre- and post-quizzes across the core curriculum, but that work is still in progress. Until then:

• Treat quizzes as bonus mastery checks where available.
• Do not assume that a missing quiz means a phase is incomplete.
• Use assignments, challenges, and notebook exercises as your main self-checks in phases without quizzes.

How to Use

For Learners

1. Before starting a phase:

   • Take the pre-quiz if one exists to assess your baseline knowledge
   • Review your results to identify what to focus on
   • Don’t worry if you score low - that’s expected!

2. After completing a phase:

   • Take the post-quiz if one exists to validate your learning
   • Compare pre/post scores to measure progress
   • Review incorrect answers for deeper understanding

3. During review:

   • Retake quizzes after revisiting content
   • Aim for 90%+ on post-quizzes before moving forward

For Maintainers

• Use pre-quiz results to identify weak spots in the curriculum
• Track post-quiz results to see whether explanations and notebooks are landing
• Identify common misconceptions from wrong answers
• Update quiz wording when content or phase ordering changes

Quiz Platforms

Current quizzes in this folder are Markdown-based. Additional formats may be added later.

What Comes Next

After using the quizzes in this folder:

• Return to the phase you are currently studying and revisit the exact topics you missed.
• Use assignments, challenges, and notebooks as the main mastery checks when a phase has no quiz yet.
• Follow the master study guide for overall navigation instead of treating this folder as a separate phase.
