Stuck in practice test plateau

Disclaimer - I work full time + have two volunteer leadership roles and many weekends end up volunteering or committing to additional stuff so I know I don’t have the most time to commit to studying, plus every test I’ve taken has been after work, usually on a Friday (I do not recommend, I am always so tired and it’s hard to think lol) but I am frustrated with my test scores just not getting better. So far I’ve scored, in order:

161 (diagnostic), 166, 165, 164

Which don’t get me wrong. Not unhappy about these scores! But I feel like I should be improving rather than hovering around the same score? I always always always review my answers, both right and wrong, and try to pinpoint flaws in my strategy, but somehow I’m stuck getting 2-4 Qs wrong for LR and 5-7 wrong for RC every time (if I get 21/27 on RC again I’ll lose my mind).

Any advice? I do know what I have a hard time with ‘what can be inferred’ questions in RC and LR and ‘find the similar argument style’ in LR (with this one I usually end up wasting so much time). I’m also a very fast reader but still end up dancing with time on RC, mostly because it takes me too long to decide if an answer is wrong.

This is a half vent/half asking for advice. I’m testing in June so I only have a few weeks left. Would love to hear your thoughts!
