Didn't work that way in Nova Scotia. You are handed something random - no choice. You need to know how to prove it safe, identify ammunition for it, and secure it.
If you have that sort of test in your region, use the break times in the course to become familiar with every type of firearm. If there is a semi-auto shotgun, don't lose a fingertip in the action when you figure out where the bolt release button is. Some classes avoid stocking the semi-auto shotgun for liability reasons, but the place I went had the attitude to prepare you for everything rather than be too protective.
