教务处的老师， 我的《现代软件工程》 成绩已经录入完毕。我会在下周一交打印文件。
下面是我使用成绩录入系统的反馈。 希望你能在百忙中转交清华网站相关部门。
谢谢。
1) speed:
when access from out of the campus, the speed is very slow.
2) when i finished entering all scores, and click "save", the web page was reset to the log on screen, and one-time password expired, i can't log on any more. as a result, all my input was lost. i have to redo it again.
3) the UI has some bugs for browser running on Win7 (the OS language is not Chinese), i can see most text in Chinese, but still some of the text is displayed as ????. The IT team should use unicode.
4) there are many web special terms in your UI, it's hard for teachers who are not familiar with these terms. i suggest the UI team do some user study to understand the pain points of users.
there are errors thrown at the user like the following, you should display a friendly message to user under error condition.
