Hey @Krtkn99
SCORM modules require you to close the windows to mark them as completed. You can find this note at the bottom of your Course Description in most cases.
Note: For SCORM lecture files, please ensure that you close the SCORM window after completing the content. Do not click the ‘Next Lesson’ button, as doing so may prevent the SCORM module from being marked as complete.
Once you have read the material and have a clear understanding of the contents then close the SCORM window to mark it as completed. Attached the reference image for the close button.
All the very best for your DE Professional journey!!
