Further maths vs Edexcel maths

hi
I'm in year 11, so I'm taking my GCSEs in a few weeks.
I was just wondering if anyone knows what the overlap between Further Maths and Edexcel maths higher is?
if I just revise from my further maths revision guide, will I be prepared for Edexcel maths?

Which further maths qualification? Do you mean AQA Level 2 further maths?

Whatever the qualification, you must prioritise normal maths since that's the only thing anyone will care about in the future. If you are not already at a comfortable grade 9 then for now stick to single maths textbooks, revision guides, resources etc. There is some overlap and doing FM questions is great for practicing hard single maths questions but you must not only use FM resources to revise single maths.
