关于TIMETABLE能否修改:
我发邮件去问过了,学校答复如下:
You can make changes to your schedule by logging into SIRIS and clicking on the "Registration Options" button. On the next screen you can select the class you would like to move, and click on the "Change Subject Time" button (at the bottom of the screen). Any available sections of the same class will appear on the next page.
