Hello guys, time and again I have said that practice questions and mock tests are an integral part of passing AWS certifications be it AWS solution architect or this AWS developer associate exam. They not only help you to prepare in an exam-like environment with time constraints but also reinforce and solidify whatever you have learned from online courses, books, tutorials, and white papers. It doesn't matter whether you have joined AWS developer courses like Ryan's course on Udemy or Stephane Maarek's course, unless and until you have practiced enough problems, you are not really ready for the exam.
