I have my Stage 1 at the start of February and I too have been looking at these. They are fairly difficult to try and visualise and I'm not sure there is any easy way to do it, just lots of practice.
You just need to try and work out a way of doing the puzzles that works for you and keep practising that technique until you get quicker and more confident at completing them!
I'm sure it won't be that bad tho! Good luck!
