How to unlock the Duelling Dervish achievement in Harry Potter for Kinect - Definitive Guide

I had a bit of trouble for this one, a couple of the characters would not show up. I had to keep restarting a duel in the D.A section to get Cho to show up.

So here is a list who I defeated
Students: Oliver,Cedric ,Draco
D.A: Ginny, Cho, Neville, Luna
Hogwarts Staff: Snape, Quirrell
Order : McGonagall,Dumbledore, Sirius

If you are still having troubles.The first time I completed all of these, I still did not get the achievement. My only guess was when I left the screen sometimes it would drop me to guest. So I just made sure my name stayed logged in and defeated them all again and the achievement popped.
Have no idea if this was just a fluke on my part but hopefully no one else has troubles.
**Also not sure if Multi-player duals count, had already done them before trying for this achievement.

Thank you so much for this! I was trying to figure out who I was missing and I'm only missing Ginny.

Even though I completed all of these, still having trouble having it unlock. I'm wondering if this has to be done in one sitting?

I'm missing Draco but after a couple of hours of play he never showed up. Anyone know if he has to be unlocked in someway?

I was a "guest" and hadn't done the multiplayer duels. Had completed everything else but the challenges before doing this (avoided 2 multiplayer stuff by doing the first one as soon as it became available)

Required some restarts before I got each on the 4 different duels but didn't take too long.

changing characters in "Polyjuice potion" would help. I get Cho with Flair Delacure

It didn't unlock for me after beating all opponents. I beat Snape and Sirius yesterday and then did the rest today but it didn't unlock until after I beat Snape and then Sirius again. I'm not sure why it didn't unlock but maybe all opponents need to be beaten in one sitting. Just glad I got it. Got sick of trying to get all of the opponents to spawn over and over again.

While in Dumbledore's Office, go to the blackboard and select it. Go to the dueling section and defeat each person from each group. 

Students: Oliver, Cedric , Draco 
D.A: Ginny, Cho, Neville, Luna 
Hogwarts Staff: Snape, Quirrell
Order : McGonagall, Dumbledore, Sirius

It is random who you will be matched up with, so just keep quitting and restarting until you get to somebody you have not fought yet.
