A good trick that has worked for me ( I scored an 8 on kaplan diagnostic and now I am averaging 10-13 on my AAMC verbal) is to spend 3 minutes reading the passage and then 1 minute per question. . For verbal,3 passages, so 3 minutes per passage*7 passages = 21 miuntes reading, and then 1 minute per passage so anywhere from 40-41 minutes per question. That is 60-61 minutes for the entire verbal test which is the time you have. You could also do this for PS/BS just modify it to 2.5 minutes for PS/BS passages. That means that you read all the passages in 17.5 minutes and then you have 52-52.5 minutes to answer the 52 questions.
