I've sent my TMA 02 off, four days early. While I wait for results I shall give serious consideration to whether it's worth continuing with this module. Our tutor group is still dismal, thanks in part to the attitude of our tutor. With the OU there is always this element of pot-luck, which is a disadvantage of their system, because if you don't have a good tutor and your group forum is inactive it is such a huge disincentive.
Maybe I was lucky on A174. The tutor and group forum were both good and the course itself was very enjoyable.
