This glitch only works for the Road to the Masters mode and works for all of the tournaments, but is the most effective when used on the four star tournaments and the major championships. Before starting the round, set the difficulty at Tournament and play only the first hole. When the second hole loads up, save and exit from the tournament and go back to your options screen. Then, change the difficulty from Tournament to Amateur and proceed to resume the tournament by hitting the X button to resume and play holes 2 through 17 on Amateur. On hole 18, Save and Exit again, return to the Options screen, and switch the difficulty back to Tournament. Then, resume the tournament by hitting the X button and play hole 18. By doing this you will receive the XP payout for playing the tournament on Tournament difficulty even though you played 16 holes of the tournament on Amateur. Average XP payout is 25000-35000 XP and, as an added bonus, the very first time you do this glitch you get a difficult to obtain No Focus pin and the "Tournament Pro" trophy.
