Sometimes when a PowerPoint gets uploaded into Create-A-Course the fonts and styling looks a little bit different than how you had originally made it. This may be due to using custom fonts that isn't installed on our site. There are thousands of fonts available, and many of which have licenses requirements that need to be met. As such we have hundreds of usable fonts available in Create-A-Course, but not all of them.
If you encounter this we recommend saving your document as a PDF and creating a course with the PDF. With PDFs the fonts are embedded inside that document which allows Create-A-Course to use to that styling exactly.
