Feeling Defeat Over RC - What to Do

I am registered for the July LSAT. For LG and LR, I tend to get 80-90% of the questions right. For RC, I am missing nearly half. It is definitely a timing issue, but also I am missing way too many questions that I do attempt. How have you improved? This is killing my score, and I am fearful this will be further exacerbated by the LSAT Flex scoring. Should I turn my focus to drilling RC sections over this next month?
