I just went to the AUAf. They said I've got to pass TOEFL with minimum 500 scores, and also, I have to pass a 12-credit semester in there. If my results are satisfactory, I am going to be allowed to transfer my credits from Kardan, otherwise, I have to start from the beginning.
Even in that case, I would not give up. I am pretty sure, I am not going back to Kardan, again.
