Unlucky circumstances

Nymphadora had just received the Ministry's owl and apparently they had 'accidently' over looked her grades at Hogwarts and put her in the Auror program. This means that Nymphadora has to retake her NEWT exams at Hogwarts to actually continue being an Auror.

It looks like she is going back into Hogwarts to complete her NEWT exams.

Well at least Harry Potter and some of the other decent children are going back into their eighth years.
