Try reassigning the student object rather than setting properties of it.

public static void SetStudent( ref Student student )
{
    student = new Student();
    student.Age = 16;
    student.Name = "StudentY";
}

public static void AnotherStudent( Student studenta )
{
    studenta = new Student();
    studenta.Age = 12;
    studenta.Name = "StudentX";
}

Don't think of ref as "passing by reference" because all reference types are passed by reference. Think of it as "reference to this object can be reassigned"
