What resources to use for CARS?

Hi everyone!

I know that practice is the key for CARS section on MCAT. From what I've gathered by reading on SDN is that AAMC CARS Volume 1 and Volume 2 is great to practice passages for CARS. But, I also want to use another source to practice for CARS. Which books do you guys recommend that match the level of quality and difficulty with AAMC (Kaplan, TBR, TPR, etc.)?

Thanks in advance!
