Common Questions About the Microsoft 98-373 Exam
The 98-373 exam, officially known as Microsoft Mobile Development Fundamentals, is the Microsoft test that leads to the Microsoft Technology Associate (MTA): Mobile Development Fundamentals certification at the Fundamental / Entry level. Passing it validates the skills employers expect from a certified professional. It is also associated with related credentials such as MTA: Gaming Development Fundamentals (98-374).
The 98-373 exam contains 30–40 questions, and you have 45–65 to complete them. Work out your per-question pace before test day, and flag slow items instead of stalling on them — time pressure, not knowledge, sinks many first attempts. Timed mock exams in the Actual4Exams test engines are the most reliable way to build that rhythm.
The passing score for the 98-373 exam is 700 / 1000, and the official registration fee is USD 127 (varies by region). If you miss the mark, a retake means paying the full fee again, so book your seat only when you are ready. A practical benchmark: score consistently above the passing line on timed practice tests before scheduling the real exam.
