My strategy was to read the passage at a moderate pace while underlining definitions, key people mentioned, and other parts that seemed important. I then answer all of the easy questions. Then I worked on the harder ones. Since you can only spend about 8.5 minutes on each passage, you have to pace yourself really well. If any questions remained after 8.5 seconds, I just guessed and moved on. Unfortunately, there isn't enough time to analyze each question like on a school test.
I hope this helps
