I did the predecessors to both courses (A103 and DD100), and I would steer well clear of any of the OU Social Sciences courses.
My history degree was brilliant and all the course materials were presented in an objective manner, can't talk for AA100 but A103 was absolutely brilliant. DD100 was a crash course in left wing thought which I found both patronising and offensive. Only my perspective though, plenty of people probably enjoyed it..............
