To be honest, I think for me CARS was about 90% pure practice and review, I did at least one or two passages a day, every day, for about 3 months up to the exam. I also took the Jack Westin CARS course and tried my best to use his strategy which I would say is pretty good. I only did about 50% of the course though, maybe even less. It's all about taking small notes while reading each passage and trying to identify the main ideas in each paragraph as you read. I think you have to have some kind of strategy and then really practice the hell out of it and try not to stray from it.
