Finding meaningful improvement in one week is pretty tough. The good news is your already pretty close to your target. It's not totally unfeasible that a 'good day' could get you the points you need.
For broader verbal review, if you're willing to put in more time, you have to be very specific on why you missed a problem. In general people don't ask the question, 'how I am reading/interpreting language' enough in verbal.
For CR and RC, there aren't really 'rules' or formulas to memorize. You have a passage, a question, and your own thoughts. And you have to pinpoint, when you struggle on one of these problems, why.

More likely, you're not reading structurally and noticing the chance to apply these rules. You have to build certain 'trigger words' that tell you to check certain structures, and you need to have a good *structural understanding* of a sentence.
