Where is Dexter on the bratz 4 real ds game?

Ok i was stuck a long time on this but i finally figured it out. First, go to the school. then, click the map button, which looks like a little compass. the star represents where you are. click on the little pink dots on the map until you see one that says Room 101. then walk all the way there, using the map as your guide. Inside the room, near the front, you will see a guy named Jeff. talk to him and he will agree to play. then go to lauren in room 102 and tell her you found a band.
