The history postgraduate entrance examination is now a national unified examination. So review several courses: English, politics and specialized courses. Note that this specialized course is a comprehensive course. No matter which direction you take, you need to look at the ancient and modern history of China. The world's ancient and modern history should be comprehensively reviewed. It's nothing special to read it several times, but you must read it carefully and recite it more. The national paper is always like this, with a wide range and detailed points, but it is not profound, which is still beneficial to many professionals. Whether you want to enter Peking University or not, it's still quite difficult. There will be many people trying to get into Peking University for the first time, and the second interview will be fierce. Therefore, you need to have a good professional quality, not just memorizing textbooks. Usually, we should also pay attention to some academic books and articles, otherwise the second interview is likely to be screened.
Let's review English and professional courses early, politics is not urgent. Wait until the exam outline of the year you want to take the exam comes down.
