Build a good swing first. Get it on plane and work on good ball striking. Go to the range with a 6 iron and work on nothing but building a solid and reproducible swing. Pick a target at a distance that is consistent with your SS and work on accuracy and trajectory. Once your fundamentals are solid work on your short game....putting, putting, putting and wedge play. Work on wedges at the chipping green from different lies. Above the feet, below, on the edge of first cut, in the rough, uphill and downhill. Practice using an 8 iron around the green, practice a SW. Then work 100 in. Each session always begin with the 6, be sure your new swing is still on plane, making good contact and reproducible. Once you have mastered this, try a tee shot at the range utilizing the same tempo as your six. Pick out a spot (be realistic) and work most on accuracy and trajectory. Put it in play and you're money.
