Simulation test on physiology (Constanzo)

Instructions:

  1. Turn off your mobile phone
  2. Do not use any book, internet and/or notes
  3. The test is supposed to take 03 hours, then make 03 breaks of 05 min between hours.
  4. If you need more than 03 hours to answer all questions, take it.
  5. At the end – when the right answers will appear – take note of those questions you’ve got wrong.
  6. Passing rate: more than 70%.

GOOD LUCK!
