The passing score for the H35-831 exam is 600 / 1000, and the official registration fee is 300 USD. Remember that an unsuccessful attempt means paying the full 300 USD again to retake it, so booking too early is the expensive way to find out you are not ready. Test yourself with the Lead2Passed practice questions first; once you can clear 600 / 1000 comfortably on timed runs, scheduling the real exam becomes a much safer bet.
