Dear student, here attached the results ot the exam of TMM of 24 January 2017.
I checked twice your responses. A suggestion for most of the students is to study my slides and lectures and not only the "tickets" that some of you exchange themselves. The mistakes are too many and always the same!!!!!
As concrening the Cu instead of Si mistake, I take in account your correction and evaluated the response consequently. But the response not ever was the right one.
