Struggling with Implied / Stated questions across all passage types

My RC score is the only thing really holding me back from breaking into the higher 160s and low 170s and I find that like 80% of the RC questions I get on a PT are implied or stated questions (mainly implied). There's only one page in the syllabus for implied RC questions and I am not really sure how to drill them, does anyone have any advice about how to improve on these types of questions or what to do to practice them more often?
