While practicing, work stricktly on form. Don't worry about where your arrows land. Focus on one thing at a time such as keeping your grip the same from shot to shot, then work on your alignment, then your anchor, etc.
Some feel that you should work on one thing for an entire session. Others think that you should work on each part of your shot sequence during every session.
You do have a written shot sequence, don't you? If not just write out the steps that you do on every shot. It will help you make them consistent from shot to shot.
A good coach will help you get this done a lot faster. Unfortunately, they are hard to find.
Good luck,
Allen
