Hi Lorraine Horine,

Thank you for your question!

Yes, you can change the font size of the questions and answer options in a quiz included in a PowerPoint presentation. To do that, you just need to go to Slide View --> select a text box --> change the size (please see Screenshot 1).

You can change the font size on one slide and then apply it to other slides using Themes. Here are some help docs: https://docs.ispringsolutions.com/ispring-quizmaker/managing-themes-35667201.html.

Hope this helps!
