Do you need to borrow an iPad or Chromebook?
Dear student,
In the coming days we will be receiving a limited supply of Chrome Books and iPads to lend out to students who need them in order to continue their classes in this new online setting. They will need to be returned at the end of the semester. We want to be sure to get these to the students who most critically need them. Therefore, if you already have a laptop or desktop at home, or other resources to continue taking classes online, then please do not respond to this.
However, if it would be impossible or very difficult for you to continue online classes without receiving either a Chrome Book or iPad then please let us know by filling out this online survey right away.
