7755 Underline the primary key for that relation, then normalize it to the third normal form (you can indicate the second normal form if you want).
7760 Identify a possible primary key for that relation.
7761 Then, using that primary key, decide if this relation is in second normal form. If it is not, identify a functional depency that prevents the relation from being in second normal form.
7762 Finally, normalize it to the third normal form.
7756 7763 Try to pick meaningful names for your relations. Try to pick meaningful names for your relations.

8341 The primary key would be \{StudentID, Term, Major, CourseID\}.

8350 Numerous functional dependencies prevent it from being in second normal form, for instance StudentID $\to$ StudentName prevents the functional dependency {StudentID, Term, CourseNum, Major} $\to$ StudentName from being full.
