GMAT Critical Reasoning (CR) | Critical Reasoning HELP!

Hello GMATers,

I'm scheduled to take my actual GMAT exam in less than a week. Today, I completed one of MGMAT's verbal CAT exam and scored a 35 on the verbal. My assessment shows I'm scoring 73% on SC, 78% on RC, and meager 29% on CR.

I've studied MGMAT's CR study guide AND Powerscore's CR Bible. I can't seem to get it right. Please advise how I can improve my CR score.

Thanks a bunch!
