I need an SQL to produce the result as shown in EXPECTED RESULT

There are three table which must be combined to produce the result as "EXPECTED RESULT". I have been trying several SQL statements with COALESCE, XML PATH, etc... but to no avail.

Any help is greatly appreciated

Course table

21                  Math
22                  Chemistry
23                  Physics
24                  History

Student table
Student ID2            Name2
1                        Joe
2                        Mary
3                        Peter      

Attendance table
ID1            ID2
21            2
21            3
22            1
22            2      
22            3
23            3
24            2
24            3
