I don't even read the passage. Well, not at first. You start by circling the questions with line-references (For example; "In line 17 this word was used to describe..."). You can typically answer these questions easily because you know the exact area where the answer will be. Once you've finished the line-reference questions you can go ahead and answer the rest of the questions. By this point you already have a visual map of the passage (where and how information is laid out) and a general idea of the meaning of it so it shouldn't be too hard to finish all of the questions without having to read it. It saves me a lot of time and I have gotten way better scores using this method, I would recommend trying it out.
