An easy way to win almost any fight or duel is to cast Levi Corpus or Petrificus Totalus. Then, just charge your Stupefy until it chimes twice, and release it. It will result in a one hit victory until later in the game, then it will require two. Note: This does not work on Fenrir Greyback.
Use the following combo to defeat any enemy. Use Expelliarmus to knock them down. Charge up your Stupefy. While getting it charged, walk directly next to your dueling opponent. Fire your charged Stupefy for a one hit kill. This trick can give you five stars for the challenge very quickly and easily.
You can get a large amount of Mini-Crests when you have used the Luck Potion and are making your way to Herbology. At this point, every time you use Diffindo to get the Mini-Crests to appear, you will get the full amount of Mini-Crests available, due to your luck. Get as many as possible at this point to help reach the 25,000 pieces goal.
Find the crest you want to knock down. Cast Wingardium Leviosa on the object you want to use to knock it down. Note: This object can be anywhere and does not have to be in throwing range of the crest. Using either a Dung-bomb or an Exploding Cauldron is recommended. Once the object is in the air, hold [Run]. You can now walk around the castle and grounds while still carrying the object in the air. Make sure that you keep [Run] held until you get to where the crest is located. Note: During this time Harry will not run fast. Throw that object at the crest to knock it down.
Playing match is very easy. You must fly through all the stars in the sky to catch the snitch. Passing all stars is not required if the star's color is going from red to light. This indicates your time is going over, so try to pass through most of the stars in the sky.
Go to the Rewards sub-menu from the Main Menu, where you see the two choices, Badges and Credits. Using the d-pad, enter the following code to unlock everything: Down, Left, Left, Left, Left, Left, Down, Down, Right, Down, Left.
