Hello, I just finished the exam a few days ago. Well, 3 14 has three parts: advanced number, linear generation and probability statistics. The content is similar to the number three, but the more troublesome parts such as infinite series, positive definite matrix and quadratic form are not tested. You are right to review on the count of three, because it is difficult to count farmers this year. Take the textbook and the complete works of Erli! When I took the exam, I found that the difficulty was really much greater than before. Wish you success! ! !
