Good product, but some wrong answers – AWS Certified Solutions Architect Review

I ran through the questions and most were great, but some were wrong, such as what VPC stands for. Most of the questions come from the FAQ for the relevant service. Update: the developer has been great at responding to suggestions and errors and updating the app. Several of the concepts (not questions) came up on the exam and the practice and information was very useful in helping me pass.
