Read these guidelines on how to write better test questions.
Test your question writing skills with these questions. Click on each question to see if it is a good question or a bad question. If it is a bad question, there will be an explanation of what makes it a bad question. Some will have recommendations of what could be done to make them better questions.
We would also like to recommend this site of the National Board of Medical Examiners. Their handbook of how to write test questions is excellent.
