Judging from the difficulty coefficient, the number one exam is more comprehensive, with high number, line generation and reading guidance, and the topic is more difficult. Count two needs no introduction, and the topic is easier than count one. The number three exam is also very comprehensive, and the difficulty of the topic is not much simpler than the number one.
Matters needing attention in postgraduate mathematics
Do one question and draw another, don't wait for the paper to be finished. Before you draw each question, you must have a look at it. Don't think that A is drawn with B, make sure that the questions are drawn immediately, and the uncertain questions are drawn after 8 questions are finished.
Take a look after writing the answer. If you find that the answer may be incorrect, you must check it immediately. For example, the area and volume are negative, the derivative of indefinite integral is not equal to the integrand function, the general solution of the second-order differential equation contains only one c, and one of the two values calculated by the parameter is nine times out of ten to be discarded.
