The Exercise
The exercises are a mix of "multiple choice" and "fill in the blanks" questions. There are between 3 and 9 questions in each category. The answer can be found in the corresponding tutorial chapter. If you're stuck, or answer wrong, you can try again or hit the "Show Answer" button to see the correct answer.
If you don't know PostgreSQL, we suggest that you read our PostgreSQL Tutorial from scratch.
