Hello there !
I’m wondering where can I get some DFIR exercices with Autopsy ?
I would perform this software 
I mean , more we train , more we get confident with this software !!
You could always download sample Android and/or iOS images from Josh Hickman:
They’re pretty regularly used in the DF realm.

Take a look at the Digital Corpora images as well!
Thanks you guys
I’ll check that !
