I did take this into consideration. I did not count, but I figured that there were not twice as many CSE grads as there were IOE grads.
Where is the information that shows that curves are generally higher? I don’t think that is the case (I could be wrong though). People bring this up, but I want to see definite numerical evidence.
Based on what I have heard, IOE classes have higher exam averages. However, if the average is an 80% and you get an 80%, you are probably not going to get a great grade. If you are in an EECS class with an average of 60% on an exam and you get an 80%, you are probably going to get a great grade.
I have graded for multiple IOE classes and I can tell you that not everyone gets >90%. I have probably graded assignments where there were not many >90% scores.
