The best way I believe to approach this section is by:
1) Skim the passage first so you have a general idea where ideas and information are located
2) Everytime you read a question, read the entire paragraph in which the answer is located (this way, by the time you have answered all the questions you will have read the entire passage)
3) Don't stress, if you can't find a answer, quess on it, mark it, and move on.....when you are done with the test and have time left, just go back and see if you can find the answer.
4) Always elminate answers you know are incorrect, and I mean always eliminate incorrect answers.
5) If you need to study for this section just keep reading for fun, and do a practice test here or there whenever you feel like it.
Hope this helps, I know you are going to do great.....keep up the hard work!!!!
