Just to add to this thread, I've just completed TU100, and didnt read anything after block 1 unless it was a specific of a TMA.
I understand that there is a need to get people to study and structure assignments in certain ways, and to raise standards to an acceptable level for degree level study. I find this acceptable as the general consensus is level 2 and 3 is much better, and much more rewarding, and as they are the only levels that count towards your degree classification then it works ok.
That said, the content on TU100 was depressingly dull, and doesnt inspire you to study, and at nearly £3k its a lot of cash I felt was wasted.
Bear in mind I didnt read the blocks, I have it on good authority, that Sense was quite interesting, however the TMAs/EMA were too easy, as they required no real depth of knowledge to gain almost perfect scores. This was the one element of the course that could have really helped to inspire learning, but because you didnt need to know it then it felt rather wasted.
Tutorials, Day Schools, and online tutorials are luck of the draw somewhat, I had 3 tutorials (2 hours each) and an introduction online tutorial, that repeated the 1st face to face really, others had 5 x 5 hour day schools, or multiple online tutorials.
Ultimately, people mostly enroll in TU100 to kick start a degree, so they luckily have some determination, as to be honest, I would have quit if I even for one moment thought that TU100 was going to be a typical experience of the OU for the next 6 years of my life.
Im enrolled in MU123, and TM129 for October, and whilst my maths is solid enough that I dont think I have much to worry about on that course, I figured that I would use these next 2 courses to try to teach myself how to study at this level, as TU100 wasnt able to inspire me to do that.
Good luck with your studies
