Verbal Reasoning

I've been fortunate to date on my practice tests and have generally fared really well on the Verbal section. My first three Verbal scores were, in order, 41, 42, and 42.

All good scores, I know, but I am frustrated at the lack of improvement that I'm seeing. I thought SC was my biggest weakness, but after getting 13 out of 15 SC questions correct on my last practice CAT, my Verbal score didn't budge a bit. I just missed a few more RC and CR questions to offset the difference, and I was stuck back on a 42. Worse still, reviewing the three CATs, I don't really see any pattern emerging of any definitive areas of weakness, so I'm at a bit of a loss as to how to even attack the Verbal section at this point.

Given my ongoing Quant isues, I really want to maximize my Verbal score, and would like to improve to a V46 come actual test day. Any suggestions / advice for how to go above bridging this gap?

FWIW, I've done some additional Verbal problems (Magoosh & Manhattan GMAT), but haven't really done an extensive amount to date, and haven't touched the Verbal sections of the OG. Can doing a lot of practice problems really help me improve on Verbal? For better or for worse, I feel like doing practice problems is less productive on Verbal than it is Quant.
