Hello Vittoria!
In the midterm you will not have access to Excel. But the midterm is in a hybrid system - multiple choice questions are answered on Wiseflow and open question will be answered on paper. If you make some mistakes as you solve an open question, we will take your reasoning into account when grading, so you should not expect to have an exercise like that being marked as fully wrong just because you did not reach the final correct answer.
Good study!
