CHAPTER 31 of 31 SQL Tutorial — Free Course on Neotech Navigators
SQL Quiz — Test Your Knowledge is the final chapter of our free SQL tutorial course. This interactive quiz contains 75 questions covering everything from SELECT and WHERE to JOINs, subqueries, and window functions. Each attempt randomly picks 20 questions, gives you 30 seconds per question, and scores your performance. A score of 80% or higher means you have mastered the fundamentals of SQL.

How This Quiz Works

This SQL quiz draws from a pool of 75 questions covering all 30 chapters of our SQL Tutorial course. Each time you start, the quiz randomly selects and shuffles 20 questions, so every attempt is different.

  • 20 questions per attempt, randomly selected from the full bank
  • 30-second timer per question — if time runs out, it counts as missed
  • Instant feedback — see if your answer is correct with a short explanation
  • Final score at the end with a detailed breakdown
  • 80% or higher to pass — anything below means you should revisit earlier chapters

💡 Pro Tip

If you have not completed the earlier chapters yet, start with Chapter 1: SQL Introduction and work your way through. This quiz covers all topics from SELECT to Window Functions. Use the SQL Reference page to review commands before attempting the quiz.
