As soon as you hit The 100 Acre Woods, ignore all the tasks and Pooh and head towards the end. There will be a short cutscene, after that it'll ask you to Save your game. Select NO, and continue on to a boss fight again Vexen. After the battle, you'll find yourself back in The 100 Acre Woods. Complete one task, and head to the end again. You'll find yourself battling Vexen again. After the battle you'll see that you gained EXP from the first battle against Vexen and the second one. Rinse, Lather, and Repeat.
