How necessary is the addition of a keyboard for the iPad Pro for university students?

For a student, the iPad Pro is expensive. But when you consider the benefits that it provides, it becomes a much simpler choice for those that can make the most out of it. On the other hand, maybe a keyboard is not a necessary addition, given its steep price tag.
I’ll be using the iPad Pro for university specifically, i.e taking notes, watching lectures, light media consumption etc.
Could I get by without using the keyboard entirely. Are there any experiences of people who have tried this and succeeded. I’ll be using a 2nd generation apple pencil as a supplement for note taking.
Thank you!
