I am going to take my CCW class tomorrow, what should I expect and what should I know before going in?

I turned 21 a few weeks ago and I am going to take my CCW class for the state of Tennessee. I am not new to firearms so I know how to manipulate and control the gun and know how to properly and safely handle them. I have already purchased the firearm I will be carrying (an M&P 45 Shield). Is there anything unexpected I should know before going into this class and completing my shooting test or is it as straight forward as it sounds. Any advice and suggestions are appreciated when it comes to EDC as I have never tried concealing. via /r/CCW http://ift.tt/2ARQLZz
