剛剛測了一下 , 問題發生原因我不是很清楚, 從下圖可以看出
在6月15日評分時就打了 0 分, 而您該次測驗設定的 Grading method
是 First grade, 因此建議您改為 Last grade
When multiple attempts are allowed, there are different ways you can use the grades to calculate the student's final grade for the quiz.
The final grade is the highest (best) grade in any attempt.
The final grade is the average (simple mean) grade of all attempts.
The final grade is the grade gained on the first attempt (other attempts are ignored).
The final grade is the grade gained on the most recent attempt only.
