If you take the postgraduate entrance examination for history, you will only take three courses: politics, English and history. These are all things based on memory, which is relatively easy.
At that time, one of my classmates took the history department of Peking University, bought many history books, such as world history, China history, modern history and ancient history, and then read books every day. For others, just like reading novels, there is basically no need to work hard, and those who take other majors will be miserable. Every day is a math review book, and everyone admires that man.
After reading those books, I will buy some real questions from the internet to do. Of course, you can't just read history books, but also take into account politics and English. That's basically it. Later, my classmate missed Peking University by 2 points and transferred to the history department of a school in his hometown of Zhejiang.
From the tutor's point of view, liberal arts tutors especially like to recruit students from science and engineering backgrounds, because some things in liberal arts now also need to use mathematics or computer knowledge, and in this regard, science and engineering students are relatively dominant, such as history sometimes needs to do statistics. At this time, you can use MATLAB, a powerful tool, to carry out mathematical statistical analysis and even draw pictures. For you, you don't need training, just go to work directly. Can such a student teacher be unhappy?
Finally, I wish you success!
