Hey, i’m in yr13 and also do edexcel maths and geo
I would recommend doing a RAG spreadsheet (Red = topics you’re very weak on, Amber = topics you’re a bit weak on, Green = topics you’re strong on) for each topic for all your subjects using your mock papers.
For maths (i’ve gone from a C in yr12 to an A at the moment), if you’re getting reds on specific topics, you may need to relearn those topics. I’d recommend watching TlMaths/Bicen Maths/Zeeshan on yt and then completing the E/P questions in the maths edexcel textbook (or practice book) for the topic to consolidate. Also, obviously, do past papers. If you haven’t finished the spec. yet, you can do As papers for now. Also don’t forget to revise statistics and mechanics. If you want to challenge yourself, there is more difficult content on MadAs Maths (but don’t rely on this solely as you’ll need to do past papers/past edexcel questions to understand the mark scheme).
For geography (i’m on an A/B atm), make sure you know the content fairly well (make sure you understand concepts, remember your models, and overlapping topics like the IGOs) and have a comprehensive list of case studies you’re ready to use in exam questions for each topic. If you know the content well already, it is likely that you are losing marks due to poor exam technique. For 12 markers (assess), make sure to write at least 3 paragraphs and a conclusion (essential) (a brief introduction outlining your answer is also ideal, but not required and shouldn’t be done if you don’t have a lot of time). In your 12 mark assessment questions, a structure you can follow to make sure you are assessing is writing what you think the most important factor is (and why!) for your first paragraph, writing the second most important factor in the second paragraph (and why it is less important), and the least important factor (+weakness of it) for the third paragraph. For your 20 markers, do an introduction (outlining your factors and defining keywords in the question), 4 main paragraphs, and a conclusion (essential). Make sure to both agree and disagree paragraphs. A conclusion for both essays is essential because most marks come from application/analysis/assessment/evaluation, rather than knowledge.
If you revise effectively from now, improving your grades to ABB should be possible!!
