Developing Mobile Apps: 070-357 Exam Premium File as PDF & Test Engine

The 070-357 exam, officially titled Developing Mobile Apps, is the qualifying test for the MCSA: Web Applications (legacy / retired) certification from Microsoft, a credential at the Associate level. Passing it proves you have the skills employers look for in certified professionals, and it can also support progress toward related credentials such as MCSA: Web Applications.

The Microsoft Developing Mobile Apps exam gives you 150 minutes to work through Approximately 40–60 questions. That is a steady pace with little room for second-guessing, so train yourself to read each question once, flag the difficult ones, and keep moving. Before exam day, sit at least two full timed sessions in the Fast2test test engine — when the clock feels familiar, it stops being a threat.

You need 700 (on a 1000 scale) to pass, and the official registration fee is USD 165 (historical, varies by region and date). Fall short and you pay that fee in full again for every retake, which makes solid preparation the cheaper option by far. Work through the Fast2test practice questions until you score comfortably above the passing mark, then book your seat.

No strict prerequisites; intended for developers with experience in HTML5, JavaScript, and mobile application development concepts. Eligibility rules can change over time, so before you register, confirm the latest requirements on the official exam page: Microsoft 070-357 exam overview.
