                                  The 70-320 exam leads to the Microsoft Certified Application Developer (MCAD) / Microsoft Certified Solution Developer (MCSD) legacy track certification from Microsoft. It is positioned at the Professional level. The exam validates the knowledge and skills expected of candidates preparing for Microsoft XML Web Services and Server Components with Csharp.NET.

                                  Related certifications include:

                                  • MCAD
                                  • MCSD

                                  The 70-320 exam includes 40-60 (varies) questions and allows 120-180. Before test day, divide the available time by the number of questions in a timed practice set to establish a steady per-question pace. If a difficult item starts consuming too much time, mark it for review and move forward instead of losing momentum. A full timed practice session can help you decide when to move on, when to return, and how much buffer to reserve for a final check.

                                  The passing score for 70-320 is 700 (on a 1000 scale), and the official exam fee is USD 125-165 (varies by region; retired exam pricing historically). Because a retake requires paying the exam fee again, use timed practice results as a readiness check before scheduling your next attempt. If your performance remains inconsistent, continue reviewing weak domains and repeat a timed session before booking the exam.
