TM470 is the second most expensive module I've registered for. At £775 (under the transitional fees) for a lowly 30 credits, it works out at a whopping £25.83 per credit, compared to the average of around £15 per credit. £775 is over double what I paid for M208, which is a mighty 60 credits!
Why is that you might ask? And rightly so, because it comes with no hard-copy materials, and there is no exam, just 3 hefty TMA's to complete. I find it hard to justify paying this out of my own pocket, but it's mandatory for my degree program and that's that, so I'd just better get over it.
