Hi there,
Sharing assessments and work with friends can be a tricky situation.
Academic misconduct is generally about creating unfair academic advantages; such as, copying someone's work and naming it your won.
However, if you don't use the work they shared and you don't solicit it, you are not engaging in academic misconduct, but please research your university's specific policies on academic integrity.
If you're still worried, make sure to reach out to your course advisor to ensure you're following the correct protocol and maintaining your own academic integrity.
I hope I managed to help!
Best of luck,
Melanie
