Apple ConnectEd is focused on utilizing technology to provide access and equity to our students and to increase student achievement. eBackpack is a digitial classwork and homework management system utilized by Tse Gai staff and students. All assignments and class resources are available to student (offline as well as online) reducing the need for paper copies and providing students with a single source for all class resources.
