How do I parse through tough ACs?

Markmark

Hi, I've been hitting the mid-high 160's and I'm finding my core weakness is not understanding what the ACs are saying. This means the AC is using hard referential phrasing, or weird grammar like using embedded clauses without commas / run-on sentences, or the wording is just ambiguous.

I'm trying to parse the sentence piece by piece in my BR, but does anyone have any help for this issue?

My solutions so far are: parse word by word / phrase by phrase in BR, reduce the AC down to subject verb object. This is still really hard and I miss a lot of questions just because I don't know what the AC is trying to tell me. Thanks!
