I studied four books for two years. I studied two books a year. Junior year is very tired, and there are too many professional courses. If you study law, congratulations, you will have more courses than me. The key to my junior year is to look at the attitude of my major and school. If you are a graduate student or a civil servant in your senior year, congratulations, you can't be idle last semester. I'm going to write a paper next semester.
