No CARS Improvement

I've been really frustrated on my lack of CARS improvement. I've taken 5 FLs so far and have seen absolutely no positive change in my score. I've tried using EK's CARS book and strategies which everyone praises but they just don't seem to work for me. I absolutely bombed the one section of their guide where they give you just the question stems and you have to use context clues to find the correct answers. What am I missing?
