@s1m0n4 The good thing is, you don't actually need to be able to 1 per minute, if you think about it. The reasoning portion of the #EPSO tests these days are pass/fail. So, you just need to be ablet to do 6 of these in 10 minutes. That also means developing the skill to quickly realise when one of these will take you longer, and quicly moving on to the next and solving that one.So i recommend practicing these in sets of 5 or 10 to practice your judgement
