The LEED professional credential exams are given on the computer. However, one does not need to be a computer expert to be able to maneuver through the test. The computer not only records all of your answers, but keeps time for you as well. The LEED exam is very user friendly. You are able to skip items and return to them later, flag them to go back and rethink some of the questions, and change your answers after you have answered, if you feel you have made a mistake. There is a tutorial that you can use prior to taking the exam to familiarize you with how everything works on the exam.
