Version 2.6.11

functional improvement

Study screen, Results screen
1.In the fixes implemented in learningBOX 2.6.9 and 2.6.10, it was discovered that in some cases grades were not left, so we have modified the way grades are sent. Specifically, we have modified the method of sending grades so that when grades are not sent as usual, they are resent in a different way. As a result, the number of cases where grades are not saved will be greatly reduced. For example, when there are a large number of questions in a quiz, if the quiz is restarted after an interruption in answering, it will now restart correctly.
2. The grades displayed when you return to the list of materials from the study screen may show different grades from the original grades depending on the timing, and there were cases where the correct grades could not be displayed without "refreshing" the browser.
