Why delete column  C?

Rami's request did seem strange at first because for each row, the new items
are not related to the original items. Normally, all items in a row are
related. It appears that he needs something like a report that lists
students and their marks in alphabetical order  and then a second list next
to it sorted by marks. I'm not sure why the order of the columns  in the
second list is reversed.
