If nothing works by the time you get to your test date, then you might want to just spend more time on the first 10-15 questions and try to get as many of those right as possible. If you can at least eliminate half to 3/5 of the choices, then you have a much better chance at guessing the right one.
one tip don't throw any one of the choices. be patient. try to understand the passage and choices the first time you read them. and sketch out the line of reasoning.
