Here is my error:
Repository.cs(14,30): error CS1525: Unexpected symbol `.' Compilation failed: 1 error(s), 0 warnings
There isn't a "." to remove... I am totally confused. Thanks for the help.

231,198 PointsThe unexpected period is the one before "OrderBy", and that's because the previous line ends with a semicolon, making the period the beginning of a new statement.
In addition to removing the semicolon, you'll also want to do the conversion to a list after the LINQ methods. Look at the implementation of "GetCoursesByTeacher" for an example.
