Can i use aqa maths resources for Edexcel maths exam?

Hello everyone, we bought revision guides for subjects and only now Found out that maths going to be Edexcel rather than aqa, all other books are correct except maths, and it's too late to return now, and we don't have money to buy Edexcel ones too, I am aiming for about 7 in GCSE math, so if i use the aqa resources for maths and some past papers, and yt classes too would it still be ok to get 7 or is it completely different and we must spend more money on Edexcel guide instead? Thank you
