a big mistake I made was writing notes. it eats time, and it doesn't really provide you real understanding of the passage. this is a section you're going to have to learn to strengthen your reading muscle, no matter if u currently struggle with that. have faith that you'll get better with practice.

each passage, engage with it. make predictions, even if they're random or u find out later its wrong. building engagement with the passage and use ur imagination! that gives u a mental note of the structure. it also makes it less boring.

I like to ask myself each passage what the author's views are. authors VP are really common questions. I also take a quick glance at the questions before I start reading and highlight any lines that the questions want me to pay special attention to.

I do like to make quick notes of the structure of each paragraph. example: P1: background info. P2: problem presented. P3: counterargument. P4: problem resolution, conclusion. this is key when a question asks u to refer to a line or a word. thats what helps u define them in accordance to the issue of each paragraph.

I recommend practice a section a day and blind review. this is how u figure out what problems ur struggling with and how to better fix that. the more practice u get, the more u recognize patterns and build strategy. hope this helps
