I didn't say that the school shouldn't try to correct it. In fact, I said several times that the school should try to correct it. Nice attempt at mischaracterization, though. Or was it simply a failure to read what I actually said?
For the seventeenth time, yes, it is the school's fault. Yes, they should do what they can do to correct it. Yes, it never should have happened. That does not mean that the OP doesn't take totally unreasonable and bizarre position, and it does not mean that when you get an exam, you shouldn't look it over to make sure everything is there, because what is an easy fix at the beginning of the exam becomes, as we have seen, a decidedly less easy fix at the end or after the fact.
