Then we need a structure to indicate that UMO is passed. It could be a flag in permissions tables. I, however, suspect, that we need a reference to the reason - how or why this UMO is considered as 'passed' and who authorized that.

Problem can be soled (successfully or not).
Test can be passed by solving problems within it.
Topic - well - you already answered that.
Course can be passed by passing final exam.
etc.
