Hello, I'm Altangerel. You have 27 Android questions and you need a little test for them. They are all check box so that you can choose multiple. After you finish your test, it shows all correct answers. I have done test app before. So I have a experience on that. I can do your project with check boxes. So each question has a multiple correct answers. If your question has a only one correct answer, then I'll use radio buttons. It all depends on your questions. Once you finished your test and click finish button on the bottom of screen, I'll show you how many correct answers you answered and what was the correct answers that you have failed.
