Listen to your instructor and then master the fundamentals of marksmanship in subsequent practice sessions. It's critical to develop a good foundation before moving on to fast and fancy shooting. Make sure he gets you sorted out on the various stances, grip, trigger pull, breathing, sight allignment, sight picture, calling the shot and follow through.
Speed comes with practice and experience. It's easy to overload one's skill level with exuberance or ego, so apply those basic steps of marksmanship for each and every shot until they are instinctive.
As this is a defensive shooting course, make sure he fills you in on the legal aspects of deadly force and the laws pertaining to it in your state.
