Study Advice / Diagramming

I finished my first PT since my diagnostic back in December. My diagnostic was 139 > and this PT was a 158. I haven’t studied consistently until these last 3 weeks, I’d always start and stop. Should I finish the curriculum or keep drilling and working through the Loophole as I’ve been doing the last 3 weeks?

I’m aiming for the August LSAT (I’m okay with taking September LSAT as well) and a goal score of 170+ (I know that might be highly unrealistic in this timeframe).

While taking the PT, on certain questions I knew that diagramming would help get me to an answer I just didn’t know what to diagram if that makes sense. Any recommendations on how to get better at diagramming?
