You need a laptop (or a desktop) computer that can run Microsoft Windows and Microsoft Office applications smoothly. Please note that Microsoft Windows is the only operating system that is officially supported by the university.
If you already own or plan to purchase a Apple Mac you will be fine except for possible incompatibility with the software used in some courses.
You need Microsoft Office applications to work on your assignments and presentations. You can download Microsoft Office for free from University Office 365 account.
