Pick to start a RTWC mode. Pick a decent team, i chose spain. Under central tab you should be able to see the option to sim matches when you are about to play a friendly. Click the RS button to go to the sim screen. Press A to sim to matchday. The sim will stop once you hit a training session(orange box on calendar). Press the B button and chose to play training session. The easier one in my opinion is under PACE an it's the offside trap. You must stay in the highlighted area to get points. If you top the max points it will give you the achievement. If not you get 3 tries to try again.
