We offer courses in many different formats (not all formats are available to all professions or accepted in all states). Simply put, text based courses are text on the screen that you read. If the course is also listed as downloadable, it means the content is contained in a PDF file that can be printed off and studied offline. Audiovisual courses are just that - audiovisual presentations that you can sit back and watch. Anatomical Dissection courses that utilize an interactive dissection platform.
