Free AND-402: Android Security Essentials Exam Questions and Answers
Android Security Essentials is exam AND-402, part of Android ATC's certification programme. Android ATC is a private training company in Ontario, and its own about page states plainly that it is independent and not affiliated with Google — worth knowing, because the credential names invite the opposite assumption. It writes its own AND- codes, its own syllabus and its own exams, and names no independent accreditation anywhere on its site. The exams themselves are uniform: 45 questions in 90 minutes, 70% to pass, $150, online proctored. They do not expire, but each is tied to the Android version it was written against, which dates them in practice.
