Configure 1 to 1 and many to many in 3 Entities using Fluent API

Am new to fluent API kindly bear with me. I have three entities Student, Address and Course, Student and Address should be 1:1 relationship and Student and Courses should be m:m(many to many).

My question is should i define Courses and Address entities as many to many or should i just access contacts through students if i want to know how many courses are being taken by a particular address(uni-directional association) Below are my fluent api mappings, i have moved the configurations outside. 

     public CourseMappings()
                {
                    HasMany<User>(s => s.Student)
                        .WithMany(c => c.Course);
                }

 public AddressMappings()
            {

                HasRequired(c => c.Student)
                .WithRequiredDependent(u => u.Address);
            }


public StudentMapping()
            {

                HasRequired(c => c.Address)
                .WithRequiredPrincipal(u => u.Student);

            }

How do i map courses and address entities using fluent api ,do really i need to or is the association of student & course enough?

you don't need to map courses and adresse since u can access adresses throught student-courses association . when you Access student you can get adresses so what u have done is ok .
