Yes, and for every version. FreePdfDump provides free demos of the Microsoft Developing Mobile Apps material so you can compare the PDF, SOFT, and online formats before deciding. After purchase, updates are free for 365 days, and when your product expires you can extend the update service at a 50% discount.
Microsoft Developing Mobile Apps gives you 40-60 questions inside 150 minutes. Rather than cramming mechanically, rehearse the pace actively: the FreePdfDump SOFT engine teaches through timed exercises, so flagging, skipping, and returning become reflexes before exam day rather than improvisations during it.
Passing Microsoft Developing Mobile Apps requires 700 out of 1000, and official registration costs $165 USD (varies by region). Since every retake bills the full $165 USD (varies by region) again, the sensible sequence is practice first, book second. When your FreePdfDump practice scores clear the requirement across repeated sessions, the exam stops being a gamble.
