Is it the vocab, or is it the passage comprehension?

I think for vocab you might just want to look through the Barron’s 3.5k word list. And for passage comprehension - have you ever looked at the official explanations for the Blue Books? The official explanations may give you some insight on how CB interprets the passages.
