KlawMan - if you are missing targets on stations 4 and 5 it may be because you are arm swinging your gun. Get your head down on the stock and work on keeping it there by feeling the pressure against your cheek. Then, with elbows up parallel to the ground, rotate your upper torso rather than swing with your arms. Arm swing almost always pushes the gun away from your face if you are not rotating your upper body. Once your face comes off the stock your point of aim changes and you'll miss the target.
Your lead should be to the right, about a barrel width visually, for the quartering shots, and about 2-3 barrel widths for the hard right shots.
If your range has a fifty yard stake, you can use it to set up your body position before you call for the target. On station 4 you should center your body a bit to the right of the post, and a bit more so for station 5. The fifty yard post is marked straight out, 50 yards, in line from the number 3 position.
Good luck!
