Go to Play Now and then under course select choose Paracel Storm.
Paracel Storm is by far the easiest course to get this achievement on, as it is a Par 3 course and the greens are pretty darn easy compared to other courses. Aim near the hole (if you are coming up short press
to extend your shot or
to shorten it, although this is rarely necessary if you play as Rory), and you should be able to get a good lie and at least putt it in 2 strokes. The hole you may have most difficulty with is, I believe, the 3rd hole where you are shooting over the deck of the Battleship and can't see the green. simply just shoot without adjusting your aim or power and you will get on the green and at worst you should be able to 2 putt it for par.
The biggest tip I can give for this game is to pay attention the the blue line(arc) instead of the arrow, as that is where your ball is going to go if you hit it properly.
I recommend going for the 'Full Foursome' achievement (play an 18 round of Stroke Play in Play Now with 4 golfers) whilst going for this, as it is the shortest course and also good practice! You can do this with one controller just by adding 3 additional players to play the course. (I didn't bogey with any of them)
Inevitably by getting this achievement you will get the 'Golf's Magic Number' achievement (Shoot 59 or better in an 18 hole round of Stroke Play in Play Now)
