Common Questions About the Apple Mac OS X Help Desk Essentials v10.3 Exam
The Apple Mac OS X Help Desk Essentials v10.3 (exam code 9L0-400) is the exam you pass to earn the Apple Certified Help Desk Specialist (ACHDS) certification, a credential at the Associate / Entry level. It is also connected with related credentials such as Apple Certified Technical Coordinator, Apple Certified Support Professional. If you are mapping out a certification path with Apple, this exam is a milestone worth planning around.
The 9L0-400 exam includes 73–83 questions, and you have 90 minutes to complete them. With that many questions on the clock, pacing is part of the challenge: divide your time into rough blocks as you go, and flag the items that stall you so you can circle back at the end instead of burning minutes on a single question. A week or two before your exam date, sit at least one full timed session in the GetValidTest test engine under the same time limit, so the pace feels familiar rather than frantic on the day.
You need 73% to pass the 9L0-400 exam, and the official registration fee is $80 USD (retired, historical). That fee is due again in full for every retake, which makes thorough preparation the cheaper investment by far. Before you book your seat, test yourself with the GetValidTest practice questions until you are scoring comfortably above the passing mark on a consistent basis — it is the simplest way to avoid paying for the same exam twice.
No formal prerequisites; basic Mac OS X experience recommended
