Each wrong answer is a common misunderstanding of the subject, so a wrong answer shows what isn't understood yet.
A part of the front page about making a quiz from one's own files (source material, as the form calls it, e.g. PDFs and Word documents), and how Tjaz writes good questions from them, for teachers and others who make quizzes from what they teach: four short points, each a bold title of a few words with a sentence under it, beside a small picture. "Right by your material": the right answers are true according to the files. "Wrong answers that teach": each wrong answer is a mistake people commonly make, so answering wrongly shows what hasn't been understood. "Understanding, not copying": the questions use new examples rather than the files' own sentences. Keep the titles short, as they sit in narrow columns
