There is no fixed academic system for Korean doctors, usually three years, but many students usually need 3-5 years to complete their courses, but some students need less time and can complete them in two years. Therefore, the specific number of years of Korean doctors depends on the completion of their own courses and papers, and a large part depends on the professors. If the professor thinks that students can graduate well, they can graduate early. If the professor thinks that students can graduate with poor conditions, they will delay graduation.

Generally speaking, Korean doctors are composed of two-year theoretical courses and final thesis writing. Students need to take two years of theoretical classes, then write papers, do research, finish their graduation thesis and get the approval of the professor before they can graduate. Some students may begin to prepare their papers in the theoretical stage of two years, and finish their papers after the theoretical class, which has been recognized by the professor. Then these students can graduate in two years, and some majors may require students to spend more time on scientific research and more materials to complete their papers, so these students will need more time and longer graduation time. To sum up, Korean doctoral students study abroad for about 2-9 years, with a minimum of 2 years, and most students study for 3-5 years. The specific time depends on their academic completion and the approval of the professor.

Because the courses and specialties set by doctors in Korean universities are different, and the graduation standards are different, the doctoral academic system is also different. Let's take a look at the doctoral system of some universities in Korea. Seoul National University: Doctoral programs usually last about 4-6 years. Korea University: Doctoral programs generally last about 3-6 years. Dongguk university: Doctoral programs usually last about 3-5 years. Hanyang University: Central University: Doctoral degree usually lasts about 3-5 years. Sungkyunkwan University: Doctoral programs usually last about 3-5 years. Sejong University: Doctoral programs usually last about 2-5 years. Yonsei University: Doctoral programs usually last about 4 years.

The tuition fees of Korean doctors are divided according to schools and majors. The tuition fees of Korean national universities are lower than those of private universities, while those of Korean humanities majors are the lowest, while those of medical and artistic sports majors are higher. Generally speaking, the tuition fee for doctoral studies in Korean national universities is between 30,000 yuan and 60,000 yuan, and the tuition fee for private universities in Korea is between 654,388+million yuan. Korean universities will have scholarships, giving 30%-80% tuition reduction according to students' language and academic performance. The cost of studying for three years is about 90000-300000 yuan.
