hi
work on your short game and your 7,9 and 11 o-clock swing, get them working good and know how far you hit with 7 iron down to a wedge on all three swings and only then start to go to a full swing, do not hit at 100% but use a controled 90% swing, you will see the shots drop if you get a good short game, then work on your putting.
give yourself time to improve, dont expect it to just happen it does take time and lots of pratice but pratice with a purpose.
