# Visualize and manage received challenges from a company
As a teacher or a school's manager, you can receive challenges from companies within two locations:
Inside a call: if you published one and if you asked companies to submit their challenges inside it
Inside the
ProjectStore: If you didn't create a call-for-challenges or if you are looking for public challenges, open to all.
# Visualizing challenges within the Project Store.
On top of your Oktonine space, click on Project Store.
You will find all the Public and On-demand challenges, in addition to the private challenges shared with your institution.
You can use the filter feature to refine the challenges displaying.
# Visualizing challenges within a call-for-challenges
To visualize the challenges received for each call-for-challenges, go to the Call element of your menu.
By opening a call, you find all the received challenges within the Challenges tab.
