LHI11,
I am also there on 25th March staying at Ibis.
My tip for ROT: make yourself a cube out of card and mark an 'X' on one face. On level 1, hold the cube in front of you and use this to practice until you fully understand which way the cube must move on each command. Once you have 100% on levels 1 and 2 with the cube, try level 2 without the cube. Then move onto Lev 3. This helped me fully understand the way in which the cube moves..... i now just have to be able to keep up in my head all the moves at level 3
Do you have any tips on the big multiplication & division for KRN. I thought i was pretty good at mental arithmatic until i tried the KRN....
Thanks
