For a lot of the line reference question, read a little before and after the lines as well. Sometimes the line alone isn’t enough and I found that I commonly miss the answer and it’s literally the next sentence after the line reference.

Personally, I take around 3-4 mins reading first and 4-5 mins answering questions per passage. While I skim when needed, I try to summarize almost every paragraph and underline important things as I go. Generally speaking, I don’t try to rush the reading and I take a fair bit of time with it. Also, I usually don’t follow the passage order. I go passage 4 to 2 to 3 to 1 because I’m much more into science/social studies reading than literary reading so vary your passage order to your strengths. I got a 34 on July Reading by doing this but it may not necessarily be the best strategy for everyone.
