I've been doing some practice cubes and I can easily do a lot of them (like the one in the practice leaflet) but there are a few which I find extremely hard and I'm wondering how high my spacial ability level will have to be. Here's one of the really hard ones - how hard do you find this question? (You need to say which cube/s can be made from the net).
Someone let me know if I'm not allowed to post images like this.
