Here's a fun and easy-t0-customize quiz template built using one of my favorite Storyline features: Convert to Freeform. In this case, I selected the Pick One interaction and then customized the appearance of the feedback layers using the Feedback Master to give my design a cohesive look.
*This template will work for folks using Storyline 360, the continuously updated version of Storyline included in Articulate 360. Want to try it out? Get a free trial of Articulate 360 right here.
