What should I focus on? V37 now to V41+ [Practice CAT results inside]

Hi everyone, after about two months of quant-focused studying, I'm looking to switch gears to verbal. For background, I'm a native English speaker and haven't spent any time studying verbal yet.

My test is scheduled for mid-May, so I have just under 6 weeks until G-Day and am targeting 720+. I have access to MGMAT guides, Magoosh, GMATPrepNow, and the OGs.

During the course of my quant studies, I've taken 3 MGMAT CATs:
- Feb 4: 620 Q37 V37
- Feb 19: 630 Q39 V37
- Apr 1: 660 Q45 V35 (I lost some steam toward the end of this test as I was getting anxious to see my quant score)

As mentioned above, I'm targeting V41+ on the test, which I think is doable given my baseline. That said, I'd like to know which area (SC/RC/CR) would be the easiest to improve and which area would provide the biggest score increase for me (if they are different)? I'm wondering/hoping I can just focus on one area to achieve my target verbal score?

I've linked to the test analysis across my 3 MGMAT tests below (and since I haven't studied any verbal yet, this should be a sufficient sample size to identify weaknesses?). I am scoring pretty evenly across the various sections:

SC: 58% accuracy (26/45); Avg. difficulty correct: 700; Avg. difficulty incorrect: 730
CR: 62% accuracy (26/42); Avg. difficulty correct: 690; Avg. difficulty incorrect: 750
RC: 58% accuracy (21/36); Avg. difficulty correct: 700; Avg. difficulty incorrect: 730

I did initially begin to work through the MGMAT SC guide, but found my head spinning as I have forgotten many grammar terms beyond the very basics (noun/verb/adj/etc.). I'm worried that I won't have enough time to re-learn all the basic grammar terms and rules to a 700-level before my test? At this point, my SC strategy is mostly ear. That made me wonder if I would be better off spending time grinding RC or CR instead?

Please let me know your thoughts. Happy to provide any additional test detail if it would be helpful.

TLDR: Native speaker. Haven't studied verbal yet. Looking to improve from ~V37 to V41+. Test scheduled for mid-May. Which area(s) should I be focusing on (SC/CR/RC)?

Thanks in advance.
