I notice you do not play multi-player games, such as Alt Shot where you can hone your skills without blowing up your average, and learn from others how to play strategically on tough holes.
- get the best wedges for your level- these are scoring clubs; learn how they perform on flops, chips, pitches and partial shots, esp learn punch shot distances-less affected by wind and can hole out
-learn distance control by "charting" your clubs, especially irons, as to distance with no spin, and full backspin- I use KIawah hole 1 with low wind practice mode because it is flat-then use mulligan to rehit over and over
-use the best ball for your level.-and chart with that ball
-learn how to read wind- your 25 feet to hole avg distance will dramatically improve
-learn putting distance, how to read breaks, and your 1 putt stats will dramatically improve
AS they say, how do you get to Carnegie Hall?= practice. Good luck!
