Advice on breaking out of mid 160's jail

I've made some really solid progress in LR and RC, and I'm definitely not upset with my score. That said, I am a little disappointed because I really want to break into the 170s. After reading through the explanations, I realized that, aside from a few random misses, my thinking actually lined up with the correct reasoning most of the time. Do you have any advice on what it takes to make that jump and consistently score in the 170s?
