3. Recomendations
   1. Take the exam in 3 passes
      1. First: choose what you know you know
         1. check the answer that you feel confident about it, if you feel so that is another posibility .. just move to the next and mark to review
      2. Second: Process of elimination
         1. look the answers and mark the answer you think is imposible with... for example.. i think this is imposible with S3
      3. Third: Review, Review and Review
