Import default is import everything. You can uncheck everything, but you can't check individual resources unless that section is checked. If you check a section, all resources in that section will be checked, so you have to uncheck what you don't want.
Import only imports section items from the source site if you have the same section in the target site. The current name does not have to be the same, but for example, if you only have 15 sections in the target site, then content from any section in the source site beyond the 15th section will NOT be imported. However, if you add additional sections later, the content that you imported which was intended for those sections will be there.
Grades > Single View > individual student does not show the student's name when viewing grades. It does, however, show the name of the previous and next students in the list.
Students are not given any orientation on where to see their grades in Moodle.
Out of the box, grades are ON by default. However, Waseda IT changes this default to OFF. On somewhat more basic level, the settings to show grades are in a place where teachers would never look at them. Most notably, not in the Gradebook setup.
Waseda IT sets the site upload limit is set to 50MB by default, but the maximum possible value is 500MB. On a somewhat more basic level, the settings to change this are in a place where teachers would never look for them. Most notably, not in Assignment setup.
