A level maths revision

I got my feb mock back and got a C. There’s still some topics I want to cover because I just didn’t pay attention while it was being taught, like half of integration, numerical methods, parametrics and I also want to go over the whole of year 2 mechanics again- but I also need to do actual revision aswell like past papers etc- can someone please help as I have no clue how to organise this and I just dk where to start. I’d really like an A or B in the real thing and I have like 2 months

Is this Edexcel? If so I'd work through this: https://www.drfrost.org/courses.php?coid=29
