Without seeing your swing, I imagine that you don't take divots or your divots are very small... A great divot hits it's low point about 3-4 inches in front of the ball, because of a good downward strike.
I would continue to work on hitting the middle/fat of the green though. 14 gir with long putts will beat 7-8 gir with sometimes short putts. (just get it on the green and get good at lag putting! :) )
I hear that! haha.
But if you don't take much divot, and you miss with low bullets, there are a ton of explanations on getting the club bottoming out after the ball on this site, what it feels like, etc etc. Looks up the 5SK (5 swing keys). Super helpful.
With a 14.7 handicap, definitely work on pars, then worry about birdies :)
And start a my swing thread! I think almost everyone here would love to help out a young high school golfer.
might have to email it to yourself. But you should be able to connect your phone to a computer with your charger cable and put it on here.
