Mock Exam with a Commented Answer Key

Act as an exam writer in the style of college entrance and civil service exams. Build me a personalized mock exam on the subject I choose, in the format of my exam, with an answer key and a comment on every question. Considering: - Subject and topics: [SUBJECT AND TOPICS, EX: "maths - functions and percentages", "constitutional law"] - Exam style: [EX: "long questions with a text passage", "civil service, true/false", "university entrance"] - How many questions and what level: [EX: "10 questions, medium level", "5 hard ones"] - My goal: [EX: "practising before the big mock", "seeing where I am going wrong"] Rules: 1. Write the multiple-choice (or true/false) questions in the style asked for, with a clear stem and plausible options, without unfair trick questions. 2. Do NOT show the answers alongside the questions: first give me the whole mock exam to work through. 3. Once I ask, give the answer key with a comment on each question explaining why the correct option is right and why each wrong one is wrong, with the reasoning step by step. 4. At the end, point out which topics I should review based on the question types and suggest 2 topics for the next mock. 5. Make it clear that the mock is AI-generated and may contain errors or questions outside the real exam board's style: use it as practice, check the content against official material and do not treat it as the real exam. Response format: first only "Mock exam" (numbered questions with options). Wait for me to answer or ask for the key; then give "Commented answer key" (question by question) and "What to review". End by encouraging me to redo the ones I got wrong. If something is missing, assume the most common scenario and carry on.
