Dinámica de contenido de columna desconocido

El SQL que necesitarías es:

SELECT  Course1_ID = MAX(CASE WHEN RowNum = 1 THEN ID END),
        Course1_Name = MAX(CASE WHEN RowNum = 1 THEN Name END),
        Course2_ID = MAX(CASE WHEN RowNum = 2 THEN ID END),
        Course2_Name = MAX(CASE WHEN RowNum = 2 THEN Name END),
        Course3_ID = MAX(CASE WHEN RowNum = 3 THEN ID END),
        Course3_Name = MAX(CASE WHEN RowNum = 3 THEN Name END)
FROM    (   SELECT  ID, 
                    Name, 
                    RowNum = ROW_NUMBER() OVER(ORDER BY ID)
            FROM    Courses
        ) C;

Pero con contenido desconocido necesitarías generar esto dinámicamente:

DECLARE @SQL NVARCHAR(MAX) = 'SELECT ' + 
                            STUFF(( SELECT  ',Course' + RowNum + '_ID = MAX(CASE WHEN RowNum = ' + RowNum + ' THEN ID END)
                                            ,Course' + RowNum + '_Name = MAX(CASE WHEN RowNum = ' + RowNum + ' THEN Name END)'
                                    FROM    (   SELECT  RowNum = CAST(ROW_NUMBER() OVER(ORDER BY ID) AS VARCHAR(10))
                                                FROM    Courses
                                            ) c
                                    FOR XML PATH(''), TYPE
                                ).value('.', 'NVARCHAR(MAX)'), 1, 1, '') + 
                                ' FROM (    SELECT  ID, 
                                                    Name, 
                                                    RowNum = ROW_NUMBER() OVER(ORDER BY ID)
                                            FROM    Courses
                                        ) C;'

EXECUTE SP_EXECUTESQL @SQL;

Ejemplo en SQL Fiddle

Otra forma de lograr el mismo resultado es:

DECLARE @SQL NVARCHAR(MAX) = '';
SELECT   @SQL = @SQL + 
                    ',Course' + RowNum + '_ID = MAX(CASE WHEN RowNum = ' + RowNum + ' THEN ID END)
                    ,Course' + RowNum + '_Name = MAX(CASE WHEN RowNum = ' + RowNum + ' THEN Name END)'
FROM    (   SELECT  RowNum = CAST(ROW_NUMBER() OVER(ORDER BY ID) AS VARCHAR(10))
            FROM    Courses
        ) c;

SET @SQL = 'SELECT ' + STUFF(@SQL, 1, 1, '') + '
            FROM (  SELECT  ID, 
                            Name, 
                            RowNum = ROW_NUMBER() OVER(ORDER BY ID)
                    FROM    Courses
                ) c;';

EXECUTE SP_EXECUTESQL @SQL;

Esto elimina las costosas extensiones XML para concatenar filas en columnas

Si el orden de los cursos es relevante, simplemente puede cambiar la cláusula order by en el ROW_NUMBER función.
