I need a iPad for my business and real estate classes but I don’t have money

so his year I will become a 10th grader and I need a new an iPad so I could deal my real estate and business classes so I can take notes and do my work and so I could keep up and store those in different sections. I really need an iPad so I can concentrate and keep organized and so I wouldn’t know how organized I am because like notebooks are so underrated but like the useful but since I don’t have an iPad. I don’t know what to do and since I’m 15 I just need to wait till I go back to school because it’s summer right now so yeah anyways bye.
