=== Grading workflow ===
 +
==== Base value and Formula ====
 +
Grade assigned to a student for completing an object consists of '''base value''' modified
 +
by pre-set formula.
 +
For example:
 +
Let's say we have a test, with base grade 10, consisting of 10 problems, each with possible
 +
grades of 1 or 0, and simple '''fraction''' formula. Each problem, in turn, would have base value
 +
of 1, and simple '''pass/fail''' formula. Thus final grade for the test would be value from 1 to 10,
 +
with 1:1 mapping to the number of problems solved.
 +
 +
Another example: stand-alone human-controlled problem might have a base value of 100, and
 +
percentage formula. The percentage would be assigned by teacher verifying the solution. Or
 +
there may be "direct" formula, where base value is interpreted as maximum grade, and teacher
 +
simply specifies any value up to the maximum...
 +
 +
==== UMO-grade-user relationships ====
 +
Base grade and formula are configured by Class Administrators for each UMO for which the class is
 +
signed up. For simplifying this task we will provide a way to group them and mass-configure grades,
 +
but internally base values and formulae will still have to be configured per umo per class.
 +
 +
The final grade for the UMO for the student will be recorded per umo per student per class. This
 +
means that if student encounters same version of the same UMO in more then one class, his completion
 +
information will be stored only once, and he will not have to complete it again, yet grading records
 +
for each class he encounters UMO through will be separate.
