If any one of the records in the table pertain to more than one subject, then
it is not properly normalized (i.e. designed). If you have groups of fields
that repeat, for example grade1, source1, approval1, grade2, source2,
approval2.... then it is not normalized at all.
Looking at your description (if I read it right, that all this is in one
table), then you do have that situation: for each student, in each subject,
there are many scores. The scores in turn have fields for reviewer, approval,
suggestions,.... Given this, "Scores" requires its own table, with a PK of
Student_ID, Subject_ID, Score_ID, plus all the other data.
They may well be more tables that would result if you do the complete
normalization process, and the complexity might (and that's a big *might*!)
not be as much as you think.

If a student is taking English then we need to show all scorces given and
the relationship to the previous grad or score. With each entry you must
always carrt fields of data for who reviewed it, approved it, made
suggestions or rejected the educational technique used. There is also a
comparison made to grades when the student goes into the next level of
education. For example from grade school to middles school, from middle
school to junior high and from junior high to college.
We even have to know that the student entered college and if that student
graduated or not.
The designers at Fort Hood, indicated iot was the toughest applications they
have ever seen. Microsoft consultants were amazed at what the attorney's in
Washington DC want us to keep an accounting of.
The bad data message comes from an append query. The tables are suppose to
be identical but for some reason this happens once in a while. I eventually
find out where the problem is, but it takes so long.
Thanks for the interest.
