Well, I don’t think that merely obtaining a copy of the amortization provides any worthwhile evidence so would not gain a mark. Obtaining the copy is the first stage to performing recalculations.
When writing your answer, picture your self giving imstructions to a not very bright assistant. He/she would come back with the copy and think a good job had been done. You, of course habe to point out exactly what to do, like for a sample of NCA reperform the calculations. That is the precise sort of detail you have to set out in the exam.
