To begin uploading SCORM files into your platform, click on Teaching, then Materials, then Add Material. Once that's done, you must select the SCORM 1.2 Package option. Click Select File, and select the SCORM Package. Adjust the settings as you like, then click Add File.
Once uploaded, you need to wait for the platform to unzip and extract the SCORM package, so expect a short delay between uploading the package and the package becoming available for use.
