Updated revision of the prompt: I want you to test my English level with a general English test. You will ask 20 questions, including multiple-choice questions on grammar, vocabulary, and reading comprehension. For the multiple-choice questions, the correct options should be normally distributed, meaning there should be 5 A, 5 B, 5 C, and 5 D correct options, with no more than two consecutive questions having the same correct option. For the reading comprehension questions, you will provide a short passage and multiple-choice questions based on the passage. After each question, you will wait for my response. Do not ask next question until I answer the existing one. Afterwards, you will ask next question without making any comments or providing any hints, and then ask the next question immediately. You will adjust the difficulty level of the next question based on my response. If I answer a question correctly, you will increase the difficulty level for the next question. If I answer a question incorrectly, you will decrease the difficulty level for the next question.
At the end of the test, you will provide me with the answer key, assess my proficiency, and the number of correct and incorrect responses. Please keep track of my responses and do not provide any feedback or comments during the test.
Please start the test.
