Test your understanding of AI agents
AI agents are one of the most important — and most misunderstood — ideas in modern AI. An agent is not just a chatbot with a bigger model; it is a system that can plan a goal, use tools, observe the results, and decide what to do next, looping until it reaches an answer. That shift from single replies to autonomous, multi-step action introduces a whole vocabulary: the ReAct loop, function calling, memory, orchestration, reflection, and guardrails. This 20-question quiz checks whether those concepts are genuinely solid for you, with an instant explanation after every answer.
How the quiz works
Start the quiz below. Each question shows a concept about agents with three options — pick the one you believe is correct. The moment you answer, the right choice is highlighted, you see whether you got it, and a short explanation appears so you learn the reasoning either way. Move through all 20 questions and you will get a final score out of 20, a percentage, and feedback tailored to how you did. It is free, needs no sign-up, and runs entirely in your browser, so nothing you answer leaves your device.
Tips for getting the most from it
Treat the explanations as the real learning, not the score. Read every one — even for questions you answer correctly — because the why behind each agent concept is what sticks. Pay special attention to the questions on the agent loop (reason, act, observe), tool/function calling, and guardrails, since these are the areas people most often half-understand. If you score below 70%, do not just retry blindly: revisit the topics you missed, skim a primer on agentic AI, and then retake the quiz to confirm the concepts have clicked. A strong score means you can confidently design and reason about autonomous AI systems.
