The BPM isn't particularly fast, and except for the occasional diagonal twists, most of the twists are things you've seen at lower levels (even the diagonal twists are common enough if you've played many tough songs). So, assuming you've practiced lower-level twist songs, the clear difficulty is quite low. Also, because the speed is slow, there's nothing you can't handle with brackets, so I think I cleared this even when I was a much lower-level local than a 12. However, since it's a comprehensive set of all kinds of twists, it's worth practicing if you want to work on your accuracy.
