How do you distinguish WRONG RC answers?

[meat tornado]

I've been studying for almost a year, and I have show absolutely no improvement in Reading Comprehension. I've practiced, I've read every TLS guide, gone through the Manhattan and Powerscore guides, tried the 7sage memory method, and NOTHING has helped me get better.

My issue is that most RC help focuses on retaining passage structure and reading speed. I don't need help in those areas. My trouble lies in picking out right and wrong answers. I don't understand any of the subtle nuances that make or break the toughest questions, even after I read the Manhattan help threads. The reasoning just seems arbitrary, and I feel as if I could make a compelling argument in support of the all of my wrong answer choices. Is there any method to the RC madness? I know dozens of people here get consistent -0--how?????? Should I splurge on some private RC tutoring?

I'm sorry if this comes off as sort of a rant, I'm just contemplating giving up on RC

2 rules:
1) When in doubt, pick the weaker answer choice.
2) Watch out for equivocation.

Wrong answer choices are almost always either too weak, or they feature some type of shift in what is being discussed that matters to the question.
