Hidden Passages:

I found 2 secret passages in Hogwarts this is where they are:

1. The first one is nere the Fat Lady, when you reach the Fat Lady turn left, under the bookshelf is the passage.
2. The second one is in the study room near the Gryffindor Common Room,when you enter keep going right,under the bookshelf is the passage.

Note: In the passages are the chests with Wizard Cards in them,you will need certain spells to open them.
