Insert the VaryTrajectory function into the event graph after a new projectile is spawned, and also if the original projectile bounces rather than penetrates.
You should now be able to test that the VaryTrajectory function works correctly.
In the FirstPersonProjectile tick event, add the effects of drag after the existing nodes.
For an explanation of the drag equation, see the youtube video.
You should be able to test the effects of drag now.
Congratulations! You have finished the tutorial!
