Not every lesson has a quiz, but when one does, you'll see a 'Has Quiz' badge on the lesson. After you mark the lesson as complete, a 'Take Quiz' button appears in the navigation bar. You must complete and pass the quiz before moving to the next lesson. If you try to skip ahead, you'll be redirected back to the quiz.

When you click 'Take Quiz', the quiz interface replaces the lesson view. You'll see the quiz title, description, which lesson it belongs to, and a progress bar tracking your position. The header displays which question you're on (e.g., 'Question 1 of 10') and how many you've answered so far.

Each question presents multiple choice options — click on your answer to select it. Use the 'Next' and 'Previous' buttons to navigate between questions. A question navigator grid at the bottom shows all questions as numbered boxes: filled boxes mean answered, empty boxes mean unanswered, and the current question is highlighted. Click any box to jump directly to that question.

The 'Submit Quiz' button appears on the last question. You must answer all questions before submitting — if any are unanswered, you'll see an error telling you how many remain. Once you submit, your answers are sent for grading and results appear immediately. You cannot change answers after submitting.

After submitting, you'll see your score (e.g., 8/10), percentage, and whether you passed or failed. The pass threshold is 70%. You can review each question to see your answer, the correct answer, and whether you got it right or wrong. Correct answers are highlighted in green and incorrect ones in red.

If you passed (70% or higher), you'll see a success message and can continue to the next lesson. If you visit the quiz again later, you'll see your previous score and can review your results. The quiz badge in the lesson sidebar changes to 'Quiz Passed' once you've succeeded. Completing all quizzes is required to earn your course certificate.
