@Ush: for the 26, you can see at each line, it's kinda turned in the "clock sense", idk really how to explain it. So answer may be A.
27: you look at 1st and 2nd pic of each line, you can see the lines that are in both pic disappear on third pic. idk if i explain well, but for exemple, you have 1st pic; O 2nd pic; U. Then only the line on the top of the O will stay, because there is already an entire U in the O. (lol) Answer G.
31: the 1st pic shows what lines of 2nd pic will stay same in third pic. Then you take the lines left on 2nd pic and "open" em, like symetric. Answer D.
34: idk, did anyone find it? i think i chose empty circle, I made kinda soustraction, 2inside - 2outside = 0. Cause line 2: 1in - 3out = 2out, same in collumns and line 1...
35: it's same with maths done in high school (at least in france), vectors or sth like that (vecteurs in french), you take the 2arrows, and see the average direction between both, then you have the line. Answer C, i'm sure of that.
36: idk this... i think i chose answer D, i tried to find some stupid logic when i did the whole test, and without being sure i clicked it... but probably wrong.
37: idk, really can't see any solution, i don't even remember what i chose xd.
39: same...
i'm too lazy to do the whole test, but if u're not, try to do it with your solutions + these xd let's see if someone can have 100% good lol
