When you say you graduated from high school and took a make-up exam in Japan, do you mean you were admitted to a Japanese high school?

It is ok to be included in the third year of Japanese high school after the second year of high school. The condition is that you need one year of Japanese learning experience.

The requirements of the University of Tokyo are relatively high. The test scores for studying abroad require a score of 750 or above in Dongda liberal arts (out of 800) and a score of 700 or above in science. There is a Japanese exam in the study abroad exam, which requires you to have a level of N2 or above, preferably N 1, before you can take the exam.

You also need to submit English TOEFL scores, with a full score of 120 and at least half of the scores.

The most important thing for you is to start learning Japanese, English and EJU courses now. It will be too late to go to Japan, wasting time and money. You can use senior three to go to China and train Japanese, English and EJU institutions at the same time. After studying hard for more than a year, I have greater confidence in being admitted to Dongda University. Come on, study!
