"Outstanding problems" means problems solved and submitted by Students to
Teacher that await for his resolution.
Here is the link that demonstrates how it works:
http://gateway.total-knowledge.com/~sergey/UU/ProblemsList.html
It doesn't matter which Topic those problems belong. Tests completed by
Students will be listed in the similar way.

No, we don't, Teachers do. They remove unwanted/"already graduated"/"bad
rating"/etc Students from the Course they teach, we change permissions to
TLT.

Teachers assign, for example, Problem or Test to a Student, we change
permissions using your stored procedure.

Yes it's for problems or tests.
Students have points assigned to them by Teacher.
http://gateway.total-knowledge.com/~sergey/UU/ProblemCheckSolution.html
or by UU automatically when they take time-limited Tests,
or by Teacher himself on the View Student Info page.
Teacher should be able to set points to Problems in Tests as well as
points for Test's time intervals. This is mostly for next versions,
though.

I see what you mean, but let's wait for the customer decision on
difficulty levels issue first.

Yes, it's in original specs, Teacher sets the price for Course. I think we
can add it to DB.

Teacher sets the language on a Course level only. All UMOs in this Course
will be displayed using this language.

Well, maybe you are right. An ability to assign Students to certain
difficulty levels within a Course should suffice.
