This is inseparable from its unique educational ideas and methods. Princeton University's rigorous and meticulous style of study has benefited many students. Academically, Princeton University is very strict and seldom flexible. Students who don't attend classes at Princeton University generally don't get credits unless they get special permission. The school also does not encourage students to leave school to study abroad or go to other schools in the United States for further study. In addition, the third-grade students should write a "third-grade thesis" under the guidance of the professor, and the fourth-grade students should write a "graduation thesis". Pay attention to tradition and always occupy the academic frontier. This romantic campus may be your ideal place to study. The school attaches great importance to the cultivation of students' character and began to introduce the "integrity" system in 1893. Here, all the written tests that students take are conducted under the integrity system, that is, there is no teacher to supervise, and students are completely conscious. This system ensures that students are responsible for honesty and the results of each exam by observing the oath of honesty prepared in advance.
