The answer depends on your personal preference only. Some research states that people remember things better when they write them down by hand, if you feel like that’s the case with you, opt for a paper planner. If you don’t see a difference, look at other factors. A digital planner app will send you notifications when an assignment is due. You can schedule them before the actual deadline to have even more time. That’s something a paper planner cannot do. Some planner apps can also create to-do lists for you. It’s very convenient - you see all the tasks due for the day and are able to plan your day accordingly. However, if you enjoy planning on paper, go for it. With digital planners, you have many options. Try different aps, look at reviews and read up on student forums to find the app that offers the perfect set of functions. With paper ones, however, you can arrange your notebook however you like. You can have one massive notebook that has your schedule, assignments, along with all your class notes. Or you could have a small notebook dedicated to scheduling only.
