Help! Maths A level advice

If you are having a problem with past paper questions then that shows you need to do more of them as they are always more challenging or structured differently to the ones in the exercises. From now on it would probably be best if you only do past exam questions for revision

Look at the mark schemes of questions you have no clue how to solve and if they do not explain how to solve the problem well there are yt channels that go through past papers question by question and hopefully show how you would go about solving them better.

Are there any particular topics/modules you struggle with?

Thank you so much! I struggle with integration and a bit of differentiation and a lot of the modelling questions from various topics mostly. For the exam questions I tend to struggle with questions that use k or questions with barely any numbers (I’m not sure how to explain this), sorry

The hardest integration questions are usually the ones with trig identities or substitution generally so it may be a good idea to focus on those. here are some exam questions for integration https://www.examsolutions.net/tutorials/exam-questions-integration/
They can only throw so many integration questions at you so the more you will be able to recognize when to use certain substitutions or trig identities

I guess by questions that use k you mean ones that use differencial equations or differentiation rates of change where you have to do dx/dy = dz/dx * dy/dz or something similar
differential equation questions: https://www.deltamaths.co.uk/differential-equations/
differentiation rates - of change: https://www.revisely.co.uk/alevel/maths/edexcel/questions/differentiation/rates-of-change/

By modelling questions do you mean modelling questions in the pure module or possibly modelling type questions in mechanics (or both)?
