Ipad for colleges

Hi I saw that they had the new Ipad air 2024, in a 12.9 inch ( I know it is bigger then the 11inch) I was wondering has a college student is it worth it to get a bigger Ipad or just get the smaller Ipad. Also another question is that if you have a M1 chip ipad should you change to a M2, or is it alright. Thank you.
