I just talked with the lady at TN Society of PEs. She said they do not have the results yet and she even called the board to check the results yesterday. She got the same answer as us. She was very nice anyway.
I can not understand why the results were mailed out at different time?
Same exam on same day; I don't believe the states received the results earlier ask higher application fee. If it is true, I would not mind to pay the difference.
