After getting all five Monster Book Of Monsters, go back to Hagrid's hut. Hagrid will let you ride Buckbeak. After you ride him, this mini-game will be unlocked.
Defeating The Professor Lupin
After you rescue Buckbeak, you must fight Professor Lupin when he turns into a werewolf. First, use Fumos with Hermione if she goes first. Fumos will cover Buckbeak and raise his ability to dodge attacks. To ensure that Hermione goes first, you should either equip her with the best items to make her agility the highest, or just make sure she is the highest level person and the only one with items equipped. Lupin only attacks Buckbeak. This battle is rigged so that Buckbeak always goes first, then Lupin, then yourself. Buckbeak will attack Lupin every turn, doing about 20 to 25 damage. Lupin has about 600 HP. None of your spells affect him -- this battle will rely on Buckbeak. If he dies you will lose. The only thing you can really do is use Fumos to protect Buckbeak and keep using potions on him when he gets hurt. You can also use the card combo Cracker Jinx. It does about 40 damage to Lupin.
Easy experience
To gain a group of levels at once, you must be at Hogwarts. Go up to the seventh floor. Make sure you have about 1,000 Sickles. Buy as many Cards (Chocolate Frogs) as possible. Check your Folio Universita. Go to the card combo called "Extra Exp". If you have nine of each of the cards needed for that combo (except for the far left one, which is a rare) proceed to a battle with a few very easy enemies, or possibly a Boss. You will want to have all three people with you. Use Harry to use your card combo, Hermione to use Fumos Duo or Uno, and Ron to heal. Once you cannot use the card combo anymore, defeat the Boss or enemy.
Fast way to level and get the best items
When you are at the seventh level, find the red painting(i think it's bloody baron), then go into it, once you come out, go south into a door, you'll be in the cafe, in there are many monster, find the monsters that have a look of a crab(fire crab i believe), make sure your lvl is atleast 15 and you have one of the attack all spells. fight the crab, you might see 2 kind of enemy armies, 1 is with 2 of those crabs on the outside, a spider on the inside, and the other is with the crab in the center and 2 fire lizards on the outside. you will get attacked first, if hermionie dies, run away, if she doesn't, use the lecture skill of hermionie(you'll get more exp), that is important because you need the mp replinish when you lv up. then attack them with one of the attack all spells, until only 1 monster is left, then attack wif a lv 2 single spell until it dies. this way, if you see the enemies wif 2 crabs, you'll get 180 exp and 100 gold, if you see the one wif 1 crab, it gives 130 exp and 70 gold. do it a few times and you'll be at lv 50. and sometimes the monsters drop ribbons, if you already have one for hermionie, sell it for 300 gold. this way, you can collect all the good items for all your characters. (ps: use the bloody baron picture for transportation is just a faster way, you don't have to go that way, but that is the best way of connecting from fred/george shop to the cafe.)
Get Most Wizard Cards
If you don't want to gather most of the wizard cards going around the school and looking for those chests, get like 1000 sickles and go to Fred and George in the southeast part of Floor 7. Go to "BUY" and then go to "MISCELLANEOUS(?)" and buy like 200 Chocolate Frogs. You might even get at least two of all of the cards in a card combo. You also want to get these cards to go to the west room on Floor 5 to unlock prizes and stuff (when you have all of them in a particular category; ex: Quidditch).
Harry Potter Wizard Card
Successfully complete the game to get the Harry Potter Wizard card. Use the card in battle to teach everyone in your party all possible spells and spell levels.
Leveling Up Faster
Try to run into (and win of course) as many minor battles as possible (you know the little glowing balls floating around). Winning all these will give you more experience points and level you up, making it easier to win the bigger battles.
Lupin Battle
When Lupin turns into a werewolf and you have Buckbeak and your battle with Lupin begins, the order will always be this: Buckbeak, Lupin, Hermione, then Harry Potter (or Harry Potter then Hermione). What you have to know is that Buckbeak's attack is the only one that can get past "3" damage (your spells are worthless). Also, Lupin only attacks Buckbeak. When Buckbeak is unconscious, you have lost and have to start over with full everything in the Hospital Wing. Go back outside and go back to the lake (near the Whomping Willow) where you have to face Lupin again. If you want to beat him your first time, here's what you do: make sure that you have at least two of each card in the card combo called "Replenish SP." Whenever Buckbeak's SP is btw. 100-200, use that card combo. With Hermione, just use Flipendo on Lupin for 1-2 damage, as to not waste your magical power (as well as with Harry until Buckbeak is between 100-200 SP). Slowly and steadily, you'll beat him with Buckbeak.
Mini-Games
This is a list of all the mini-games, how to play them, and how to get them:
Wizard Cracker Pop-It
It is obtained when you go to a feast in the Great Hall. This game is made by Dumbledor and is kinda like Block Breaker. You have to find a group of 2 or more of the same wizard cracker and press A when the wand is over it. You'll get it.
Buckbeak's Hippogriff Glide
Simple to explain. You get this MG during the first care of magical creatures lesson, after getting the five monster book of monster books. All you have to do is collect the golden bats.
Riddikulus Boggart ChallengeOkay, you get this mini-game during the first defense against the dark arts lesson. It's simple to play. You just have to look where the boggart is going, and make the character it's going to cast riddikulus on it. So if Neville is on the left and the boggart assumes the shape of professor snape, then you push left. For Ron you push right, for Parvati you push down, and for Seamus you push up.
Tea Leaf Divination
If you don't know how to play this mini-game, i am going to go to your house and kick you wherever it hurts. It's basically an electronic fortune cookie. Push B to recieve your tea leaf reading. To stir, repeatedly tap A. Oh yeah, and you get by opening one of the trunks in the back of the card collectors club room.
There you have it. All the unlockable mini-games. If your feeling bored, play them. If you don't have them all, here they are. Sayonara. *gong rings*
Replenish SP And MP
Every time you level up you replenish your SP and MP to their full points.

That is where the Transfiguration Classroom is (I got this game two days ealry. That's why I know where the classroom is after getting very ticked off at the game).
