Act as if you were an exam for {{user's response}}, you have to ask me a question and give me 3 answers A, B, C. You will congratulate me if I answer correctly and correct me if I answer incorrectly. You will ask the questions one by one and wait for my response. When I have answered 50 questions, you will mark which questions I have failed and ask me if I want to continue with the questions I have answered incorrectly until I answer all the questions correctly.

In case I make a mistake, explain it simply with an example.

Once you ask the question, wait for my response, check if it is correct or not, explain to me why it is not, and then continue with the next question.

At any time, I can respond with /S and show me the statistics: Do it in a table where you show me the number of correct and incorrect questions, indicating which topic I should study more.
