The documents that I remember on this game are pieces of paper that you collect all over the school. They should be in inventory.
Also you should gain "wisdom" from the first trial - that might do it also.
After finishing the trials - there is another puzzle that has books that will give knowledge - but that is later in the game.

Are you sure you passed the first trial?
Also maybe a replay might help.
Did the tree grow?
