I took a GMATPrep CAT today after 3 months of haphazard studying (there are some days i am totally into the GMAT and there are other times that i dont even study for a week mainly because of the kind of job i have) and i am not really comfortable with the score that i received.I scored a 660 (81st percentile they said) but i know that this is not the score that i want and that is not the score that i am capable of. I want to get 700 at least on the real exam and fortunately,i still have like some months to go until the real exam (planning on taking the GMAT around September or October). In the GMATprep CAT score report,i received a Q44 and a V36. After close analysis,i found out that i really need to improve on my Quant while also improving on Critical Reasoning which was the one that i got incorrect the most on Verbal.I got 4 Sentence Correction Questions incorrect (which is obviously surprising as i have always taken Sentence Correction to be my weak point) and also got 3 reading comprehension questions incorrect (mostly because of my stupid mistakes as i am really a bad ass with reading comprehension). Overall,i got 12 questions incorrect in the Verbal section but the obvious disaster was Quant. I got 20 QUESTIONS INCORRECT

but still managed to get a Q44.This is really a disaster.I found out later that i was making silly mistakes and would obviously have gotten 4 questions of out the 20 incorrect ones if i was more careful but still,that's some too many incorrect questions.So the reason i posted this was because i need help with strategies to become a QUANT master in the few months i have left

while also becoming much better at Critical Reasoning. I have finished going over the Manhattan QUANT Strategy Guides but planning on going over them again because am sure 100% that i have not fully mastered the basics and theory and after that,move on to practice.
So,can any of you guys recommend material for the Critical Reasoning. I have gone over the Manhattan Strategy Guide for Critical Reasoning and i dont think i have the urge and motivation to go over it again.I want something different but also top notch to help me get into that Critical Reasoning mood to be able to ace any question in Critical Reasoning.I still feel that my thinking on critical reasoning sometimes are haphazard and thus want to set that straight.Thanks
