The key is that you need to hit the greens in the best spots. Once you play a decent amount of times, you'll know what I'm talking about. Sometimes, hitting it to 20, even 25 feet might give you a better chance at birdie than 10-15 feet. How many times have you seen the best players miss their approach, but make a long putt? Most of the time, they miss it where they can still give themselves a good look at birdie.
A couple examples are holes 1 and 6. A little long and left on hole 1 will leave a straight downhill makeable putt. On hole 6, if you hit it hole-high 15-30 feet away, you have a little left-to-right uphill putt.
Sometimes, though, the greens just break from everywhere and you have to take your medicine. Like hole 4, if you're going for it you must aim to the right with the hole location. It just leaves a nasty right-to-lefter all the time.
All I can say is use your notebook for each hole and write down where the best places to leave a good putt are located. It may take a while to get each hole down, but it's worth it. Hope I helped.
