Also one more thing, what is the passing mark and how many questions are there on a 640-721 ?
Passing scores are set by using statistical analysis and are subject to change. At the completion of the exam, candidates receive a score report along with a score breakout by exam section and the passing score for the given exam. Cisco does not publish exam passing scores because exam questions and passing scores are subject to change without notice.
Duration:90 minutes (75 to 85 questions)
