Hi Rasmus,

Yes, I should have done that. Here is the beginning of the grading (I
removed many columns which are identical).
| Name | Grade | Question 1 | Question 2 | Question 3 |
| Coeff | 6 | 1 | 3 | 2 |
|-------+-------+------------+------------+------------|
| Foo | | 1/2 | 1 | 1/4 |
| Bar | | 1 | 1 | 0 |
#+TBLFM: @2$2=vsum($3..$>)
I would like the grade of Foo to be 10 * (1/2 * 1 + 1 * 3 + 1/4 * 2)/6
and Bar to be 10 * (1 * 1 + 1 * 3 + 0 * 2)/6

Each student is a row, an each question is a column.

Thanks, but I does not seem to do what I want. I prefer to keep the
coefficient in the column with the question name so that I can easily
know what it refers to when I adjust it.
Thanks again,
Alan
