A level resit Edexcel Maths, SNAB Biology, Edexcel Chemistry

Hi,
I did my maths a level in one year and got a C so I need to resit, I also need to sit my bio and chem so I’m gonna do all three in 2027.
I don’t know how to go ahead with this, how to start and when I need to finish everything like learning content, or how to even learn it. I’ve got the textbooks, so I’m thinking to learn the content for all three by September 2026, and then do exam questions and using the mark scheme after that until the exams.
If anyone can find any resources for me to help me out it would be amazing.

For maths, I already know bicen maths, and zeeshan and tl maths that I used last year,
For chemistry, I’m using chem revise to learn the content and then just exam questions,
For biology, I’m using the textbook and specification and then using the SNAB online topic tests, someone gave me a link.

Do you think it’s enough to get three a stars, I want to do dentistry. Also I’m gonna do flashcards while learning content.

If anyone has any other ideas or something, let me know.
