iPad for nursing school

Hey guys, I’m going to nursing school in January . I have a iPad 5, Mac book and iPhone , but I keep seeing other nursing students recommending iPads for nursing school to take notes and stuff.

My question is, is my iPad 5 going to be good enough? As far as I know, it is able to support notability but I see a lot of people getting newer iPads.

Thanks guys, I’m really nervous and just want to be as less stressed as possible. <3
