If your arrows are falling off your rest. You are twisting the string, when you draw back keep your hand straight when drawing, Keep your elbow up level with your shoulder, Using your back muscle - draw back, putting your index finger to the corner of your mouth, Open your hand and let string roll off your fingers. Stay in stance till arrow hits target. Always come to anchor. I teach my grandkids by throwing a balled up tissue out in front of them. First, practice coming to full draw and correct anchor. Once you are comfortable at that consistant anchor then you can work on shooting at further distances....Practice! Practice! Practice! you need to stay with it....it will get easier and more accurate.
