From the menu, select Golf. Choose to play the full nine holes under the rookie setting, as this gives you no wind to mess up your shots. You don't have to get under par on each shot, but your end overall score must be below par. As long as you take your time this should be no problem. I suck at golf and got it first time. Make good use of the observation feature (raise your hand to your brow) and pay attention to the tips given by the commentators, especially the american woman. These will tell you how to play your shot, and then it's just a matter of pulling it off. If you still need assistance then raise one arm to go into practice mode. You can play your shot until your happy with it. Once you have it down, simply raise your arm again to take the shot for real.
I found it easiest to get under par on the first few holes, and then I mainly got par at the end. Happy golfing!
