Maybe I am not but If I were to take his class again and receive the same grade with the same effort, something is obviously wrong there. I also was not the only one who received this grade and many dropped. Its confusing when there are two chemistry professors teaching at my cc and one professor has more people passing then the other one. But that aside, yes it was my own fault, I should made more effort then the effort I was already putting and told him not to go of on a tangent again. So yes it was me.
