Advice for RC?

Hi everyone! Im realizing that im struggling quite a bit with RC. ive gone through the core curriculum and read and watched videos, so im familiar with the typical strategies employed when doing RC but I cant seem to actually implement it. when the passage is more difficult, i find it really hard to focus on the structure and whos arguing what. also, im not sure if its just me, but i dont feel like low res summaries really help me, they just eat up my time. any advice would be great, thank you!
