I have the same problem with my advisor. I dont know whether i can change the advisor or not. I took one subject which was not advised from the regular advisor but it was from one of my professor. Siting that reason, the advisor is trying to add extra credit as i have already finished my whole credit. Now in the mean time of filing of Graduation (G-2), he cancelled my appeal and asked for extra credit. Though another professor is in my favor but i am not decided what to do. And i am trying to persuade other few professors so that i can succeed. In every case Dept. head is always crucial and can not decide in my favour. Good suggestions please.
