@missywowzer I am surprised that you felt you were unable to use other sources outside of the text. I was encouraged to do so if it was relevant to the course text and not to use too much anecdotal evidence as this is not useful at degree level.
The guidance regarding assignments is to replicate what one would receive if at a physical campus, are you saying tutors don't guide their students in this way? Apart from the fact that OU students in most courses complete far more actual assignments than campus uni, campus students receive a lot more face to face guidance which includes study pointers, especially before an exam so, I beg to differ. I base this comparison on completing 2 OU modules at levels 1 & 2 and am now continuing my study in a 'normal' university! Also, the point of a degree is to show understanding of the course one is studying so I'm not sure what you are saying regarding the quality of the courses. Perhaps this type of study is just not for you, however, I enjoyed it thoroughly and did a lot of independent research on my subject, some of which I used in the assignments. The OU does require a lot of self-motivation and an ability to set one's own timetable and research independently. It's not for everyone but this doesn't negate its worth because a few people can't work out how to make the most of it.
