It is very possible to complete a Four-Passage-Twenty-Question-Seventeen-Minute test section, only thing is you have to be at the outer limits of your intuitive abilities. One thing you should know is that you do not have to read the passages per se to be able to answer the questions that follow; all you have to do is skim the passage i.e nothing more than a fleeting run-through. Remember you still have to come back and check the passage for answers to the questions that follow so why waste time reading through the entire thing first time around. The Verbal Section doesn't test your Comprehension abilities but your skill at extracting the answers from the passages.
