Shoot your bow with the broadheads and arrows that you will hunt with...Test each arrow with a broadhead, then put a new one of the same type before you put it in your quiver...

Shoot from the stand that you will hunt from, not just an elevated stand...Shoot with what you will wear while hunting...I know a hunter that over shot a deer 3 times, he finally found out he was losing his anchor point because of the headnet...

Learn to shoot from an elevated position...You shoot over deer because:
1) The deer ducks the arrow...The only solution is to only shoot at relaxed deer...

2) You have bad form when shooting down...Not only bend at the waist, bring your nose down to touch the string, if you don't then you have raised the rear sight and you will shoot high...If you just drop your arm, you will shoot high...The correct distance to hold on is from the base of the tree to the deer...
