To correct typos or images, use the option to replace individual files via the file directory. Upload a SCORM export from your authoring tool here and not an ILIAS export file. Make sure that your authoring tool has retained the IDs in the manifest file. Attention: Even popular authoring tools cannot do this. SCORM learning modules of certain authoring tools discard learner data obtained if you change the number of answer options of questions or insert new questions. Check in a test installation whether learning statuses that have already been achieved are possible when learning modules that have already been started are called up again.
