1, the difficulty is close to the difficulty of the college entrance examination, the quality of the questions is ok, there are no strange questions, and it is suitable for keeping the feel.
2. The coverage of test sites is still relatively complete, and there will be some novel topic settings. The answer is analyzed in detail. You remember there seems to be a summary of the test sites (I have graduated, and I have brushed too many books in high school, so I can't remember clearly).
3, the typesetting is clean and beautiful, and it feels good to do it. Remember that the multiple-choice question seems to have an "upgrade track card"? Nice design, huh? You can intuitively see your own score change trajectory.
