You don’t have to do the level projects in Pathways in order. You can choose your sequence based on your interest and preferences. But everyone’s Level 2 includes some required speech projects where the specialization of each pathway begins.
Some of the projects share the same required project. Connect With Your Audience and Active Listening are in 5 of the 11 pathways, so if I were a betting woman, I’d say that about half of the Toastmasters are going to have to do these projects.
