Make sure you're actively reading throughout the passage. Each time you encounter a statement you should be shoring it up against the statements that preceded it.
Where is the author going? Are there certain positive/negative words that she/he uses? Is the point to just discuss various views, or to discuss views but agree with one? Who's side does he/she agree with?
There are a million more questions that will come up. My advice is to be very actively engaging in the passage as you read. RC will keep you on your toes more than any other section IMO. It is more exhausting to be focused that intensely with that much material than it is with short LR questions. Newer RC sections are harder too (IMO), which leaves you barely enough time to adequately assess all the answer choices.
Although I respect frybread's opinion, don't let his comments discourage you. Focus and practice. You'll be fine!
I think that's pretty much the best advice you'll get for RC.
If there's any magic formula for the RC section, then that is it.
I was pretty bad at RC as well, until I just started to subvocalize and read actively, asking myself relevant questions along the way.
By doing that, improvement was instantaneous. Speed actually improved as well.
I stopped making all the pointless boxes, circles and annotations and instead retained most of the information by
changing how I read. Though, I still underline of course.
Anyway, I sympathize with your situation and wish you the best of success.
