i am sorry if it has been an annoying post, i just wanted to find out some information about a teacher and i thought this would be a good place. Its hard to find people in campus who have taken the same class with the same teacher ....30k students attend every semester. And thank you very much for your insight about knowing some students, and for trying to help me. This guys name is Professor Fiebig, just ask and see if they know him, and if it is possible to get some feedback back. thank you so much for your time
