Multiple-choice questions here are formative—for learning, not high-stakes grading.
How to use them
- Attempt without guessing—eliminate wrong options using lesson content.
- Read the explanation after every question, especially when correct.
- Re-run the playground if the question references code behavior.
Writing your own questions
After a lesson, write one question a teammate might ask in review. If you can’t, re-read the pitfalls section.
Self-check
- Why is “lucky guess” dangerous before interviews?
- What will you do after a wrong MCQ answer?
Interview prep
- How should you use MCQs if you freeze during interviews?
Train the same habit: paraphrase the question, eliminate impossible options, then verbalize why—interview MCQs are time-bounded but the reasoning pattern matches.
- Why read explanations even when you guessed right?
Authors add nuance and edge cases you have not met yet—avoid brittle confidence.
