When I was trying to break 100, my aim was to play even bogey +1 per hole, that simply means I shouldn't play too aggressively.
On narrower holes, I'd tee off with my 3-5 irons, I seldom hit my drivers.
Also a simple course management, I know I'm weak hitting anything shorter than 80m so I try to leave about 100m for my approach.
As for putting, I practice lag putting as so that I won't have too many 3 putts.
Chipping n pitching, I usually practice the strokes in my backyard as for me as a beginner, the problem wasn't really distance control but rather the smoothness of the swing.
When I got the thing consistent n not jerky (ground, topped...etc) I started playing better.
Now my target is to break 90 consistently, recently I've been hitting between 91-93. My best score was 88, and that was from a 42 + 46.
I'm lacking consistency, and I'm working on it :)
Gluck.
