Critical Reasoning

I have been reading through the powerscore CR bible recently. When I attempted the exercise on the first strategy ( Must be true questions) I found most questions to be very difficult, much more difficult than GMATPrep or MGMAT tests. Do others feel the same too? Or do I need to step up my game?

Would like thoughts and comments based on personal experiences with the powerscore or LSAT CR.

thanks!

I found it really tough as well.

So tough, that I just got depressed and left studying from the CR Bible. So now I'm just concentrating on the OG and the questions posted on the forum.
