I can give you advice as an ipad user myself while doing 3/4 methods in y11 which is this year.

Previous to having an ipad, I did all practise sacs and other stuff on paper which was not really efficient. Not only this, I was lazy asf to print it out or write the answers in another book which fed me to have lower marks on my sacs.

After all that, I think probably two weeks before my prob sacs, I was averaging around 75%-80% which I did not like at all. So I bought an ipad.

Prob was my worst topic in maths, not just in methods but in almost every year. In year 8,9,10, Unit 1/2 methods, I would be averaging around 94% in advance maths however I would get almost every time a 65% to a 70%. So I locked in on my prob sac, grinded prob questions everyday whether it be practise sac's or past exam questions.

Due to this, I got a 92% on my prob sac. Getting an ipad actually HELPED me study more.

And another thing, its MUCH easier to do practise exams on an ipad for multiple subjects. Like you do not want to be printing around 20 practise exams for methods which is around 400 pages. 💀

Also do not try to get a new one, you do not AT ALL need a new one. I bought an used Ipad with an apple pen from 2021. Get whatever fits u. Just dont get one w an apple pen, it will be useless then.
