Hey JimmyJames,
I've been told that understanding RC is the key to a solid verbal score. Best thing to do is approach each section and learn to interpret each reading section. I'm in the process of doing that now.
OG answers help provide reasoning behind each answer, or so I've been told. I've already gone through RC questions but need to re-address because my hit rate SUCKS.
Let me know if you find anything that helps! I hear reading the Economist and the WJS helps strengthen your reading skills too.
