Before you start

Basic programming

Answer before reading

Choose an answer, explain it to yourself, then reveal the explanation. A score shows how you did on these questions; it is not a hiring recommendation or a measure of overall ability.

Turn mistakes into prompts

If you thought fetch rejects on every HTTP error, request a missing resource and inspect response.ok. If you confuse stacks and queues, trace three items through each. Small experiments replace unreliable memorization.

Keep a useful practice loop

Filter to programming, systems or testing. Finish a question before moving on. Restart resets only this session. These questions and solutions were written for SkillNexis; upstream collections are discovery sources, not copied question banks.
