Convenience with a cause

It was super convenient to make everything online, so I didn’t need to travel or move to go to school. The ‘weekly’ schedule was also very helpful. As a full-time employee, I could schedule my studies around my schedule, and I always felt like I had enough time during the week to complete my assignments.
