     • Recomendations
       • Take the exam in 3 passes
         • First: choose what you know you know
           • 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
         • Second: Process of elimination
           • look the answers and mark the answer you think is imposible with... for example.. i think this is imposible with S3
         • Third: Review, Review and Review
