If you're getting a message saying "This SCORM package is still being prepared. Please try again in a few minutes", it just means that the SCORM file is still being transferred into the SkyPrep platform and is being extracted. The conversion time is entirely dependent on your internet speed for the upload, as well as the size of the SCORM package -- the larger the file, the longer it will take to extract.

Because of this, it's highly recommended to upload a SCORM file as soon as possible to allow ample time for SkyPrep to get your course ready.
