What is the important point? Every school is different, but most of the scores are concentrated in the new three and the old three, so be sure to make it clear and recite it. We also need to learn the historical experience method to improve efficiency. What did 10 do?10/0 did? For example, 1840 is a crow, semi-colonial and semi-feudal 1860 is a crow, and so on.
In this way, some students have basically passed the exam and reached the standard of elective courses.
If you want to improve your grades, you need to memorize answers and stereotyped writing.
No matter any exam, we should grasp the key points. Personally, I don't advocate reading books, and I don't want to download notes and review them directly. It is very effective to summarize information or notes by yourself. As for the examination paper, to put it bluntly, it is very inefficient. Unless the teacher has a tutorial paper and an examination paper, it is better to summarize it himself.
