Most of the tests are at an equivalent of the level 3, some even more difficult.
RMS: same as level 3
KRN: more difficult
OWT: same as level 3, but I found it more difficult for the shape of the clocks and the way the numbers are presented
ROT: start very slow, like level 1, gradual increase of the speed until level 3, maybe even faster
SKT: level 3
VLR: level 3, very small box
VMC: like level 3, but the shapes are more difficult to remember
You have only one attempt, but in some you have a few shots for preparation.
