Consider the following modified relational schema for a university database system that manages student enrollments:

Enrollment$($StudentID$,$ Semester, CourseID, TuitionCost, Grade, Classroom$)$

Primary Key: $\{$StudentID$,$ Semester$\}$

FD$1$: $\{$StudentID$,$ Semester$\}-->$ CourseID

FD$2$: $\{$StudentID$,$ Semester$\}-->$ TuitionCost

FD$3$: $\{$StudentID$,$ Semester$\}-->$ Grade

FD$4$: $\{$StudentID$,$ Semester$\}-->$ Classroom

FD$5$: Semester $-->$ TuitionCost

FD$6$: CourseID $-->$ Classroom

Each student can enroll in only ONE course per semester.

The tuition cost depends on the specific semester offered.

Each course is assigned their own classroom regardless of the semester.

Analyze the structure and functional dependencies of this relational table and determine ALL the PARTIAL functional dependencies.
