How do you get to Wysteria in Wizard 101?

after completing the blood brothers quest from qrizzleheim. After your done, talk to Headmaster Merle Ambrose and he will let you go to wysteria. And if he doesn't say anything like that, that means you didn't complete the quest "blood brothers" or your game has a glitch or a virus or its been hacked or kings-isle did something, or something like that
