Before test day, divide the available time by the number of questions in a timed practice set to establish a steady per-question pace. If a difficult item starts consuming too much time, mark it for review and move forward instead of losing momentum.

            The passing score for H12-721-ENU is 600 / 1000, and the official exam fee is $200 USD.
