Critical Reasoning

hi guys, i am sure at least some of you have tried the questions on critical reasoning 1000

jsut want to gather some opinion, do you find the question harder than those in OG, for e.g. I think so (i hit only around 13/14 out of 20 question per test) ..i am not too sure if the reaosn why i find OG easier is because i have encountered questions elsewhere which are repeats in OG

do u guys find it worth the time to go through 1000 of the questions?

pls adv, tks
