RE: 3D Score?
Don’t get your self down, the scores will come with time and practice. By time your league is over you should see an improvement. 3-d is about 3 things- shooting, judging distance and knowing your target. You need all 3 to be really good at it. Judging distance and knowing your targets scoring rings are things you can do any were at any time. If you need shooting help find a mentor or coach they can help you over the rough spots.
Set your self reasonable goals to shoot for. Like when I started shooting 3-Ds my 1st goal was to get all kill shots (8 or higher) it took a while.
