Tokyo University, for example, uses an academic year system under which any student whose grade average falls below 40 percent can be expelled, whereas Kyoto uses a credit system that gives students from three to six years to retake or review courses no matter how bad their grades are.
例如：東大採取學年制，只要總平均成績在四十分以下，即可令其退學。京大則採用學科制，不管成績多壞，都可以三到六年（京大規定的修業年限）來複習、重修。
