How to react when a professor give back the corrected version of a test just before the finals? I'm asking this question for a friend as he is not very familiar with SE sites.

Context:

My friend, let's call him A, has a physics teacher, which we will call B.

A, as the rest of the class, had a mid-semester exam 1 month and a half ago. He thought he failed, as some of other classmates. 

A month passed, with Christmas holidays, and A had completely forgotten the whole exam.

However, yesterday, B gave back the corrected exam. My friend, and 1/3 of the class got a &lt;25/100. However, not a lot of students are between 25/100 and 65/100. 

A has his final physics exam from B tomorrow. So, he had two days to review and correct his mistakes before the new exam.

As it's the finals, tomorrow will be a big day, accounting for 20% of his entire semester. He feels that the entire situation is “completely unfair”.

Questions:


Was it ethical/fair that B gave the grades two days before the exams?
How could A, if it has to happen again, handle the situation?
Could A talk to B about his feelings?
Should A report to B superior about the situation?
Should, as a student of another class, handle the role of a “mediator” between A and B?


Comments:

A is in a small french university, where the teachers and students, and the administration know each other really well (think about 90 students in the whole building).
A is in his first year in the university, and will probably have this teacher again next semester and next years.
Was it ethical/fair that B gave the grades two days before the exams?


I find it unfortunate. However, the question about fairness or ethics does not have a definite answer, as it depends on what was announced in class. If, for example, it was announced that the mid exam was to give the students feedback on their progress, such a large delay was not appropriate. If, on the other hand, the purpose of the exam was to give the instructor a feedback on how the students digested the material, than there is nothing bad about such a large delay. I, personally, would find the latter a bit weird and think that a mid exam which is corrected but not handed back to the students timely is a waste of time for everybody. 


  How could A, if it has to happen again, handle the situation?


Ask in advance. Ask what the purpose of the exam is. Ask when you can expect the results back (and explain that you value the feedback and that he feedback will be helpful for your learning).


  Could A talk to B about his feelings?


I don't think that feelings should be discussed. However, A may bring it to the attention of B that it would have been easier for A to get the feedback earlier (or not at all), and explain how a timely feedback could have been helpful and so on.


  Should A report to B superior about the situation?


Not unless B had violated some rule. A prior discussion with B is better.


  Should, as a student of another class, handle the role of a “mediator” between A and B?


If A is too angry to discuss the matter properly, a mediator may be a good idea. However, I think that this would look rather unprofessional and that it would be better if A could calm down enough to discuss the matter themselves.

What could be a good idea, is to gather more information from the rest of the class, i.e. what they think about the situation, and then let one or two representatives discuss with B. These guys should be well prepared (e.g. with notes from the discussion of group) and try not to speak for themselves but for the whole group.
