Indeed you sound a lot like this GMAT student
who almost aced the Quant section the first time but still was in the high 600s because of a weak verbal score.
There's no perfect strategy as mentioned above. Everybody has a different style of learning. It turns out this student Kang Cao was, like you, a quant-oriented person and his score reflected that. He was waitlisted for this very reason. The admissions committee told him to retake his GMAT. In this situation when you have clear room for improvement in one section, you should consider retaking. For Kang, this was a huge improvement. Of course, he definitely put in the effort to absorb and learn a new way of thinking. If you can put yourself in the same quest for a more balanced score, it wouldn't be impossible for you to improve your score a decent amount.
Focus on reducing the amount of time you spend on SC so you can spend more time on RC and CR.
Hope that helps!
