"מבנה הקורס הוא חשוב."
Translation:The course structure is important.
Is the notion of מבנה different from that of structure ?
Despite decades working in English-speaking universities, I have never heard anything referred to as the "course construction" so my first assumption was that this is what I would call the the structure of the course.
But perhaps there is a reason for this being rejected ?
Apparently since they turned you down on "the structure of the course" they have decided to accept it; I just tried it and it was okay.
