    Greetings sir.it's me again.I'm studying edexcel 9-1 higher tier maths and I'm a bit at a crossroads on how and what to revise.absolutely no structure to my revision whatsoever.btw your doing a stellar job .a massive aid to all students doing maths😉

      Warrington Wolves Personally I would get yourself a revision guide, this will structure topics for you, alongside that I have also put a checklist together that you can find here: www.thegcsemathstutor.co.uk/uploads/4/4/2/3/44232537/gcse_maths_topic_checklist.pdf from there I would use the guide for some order and a general overview, the checklist to identify what you have/haven’t done and then the videos and playlists on this channel to access a tutorial and practice questions! Hope this helps 😁🙏🏼🙏🏼

    Hello. It's me again. Just wanted to let you know that i am very grateful for your videos. I was very ''iffy'' on Completing the Square but now i'm quite good at it even if i do say so myself. Anyway i think you should have tons more subs because let's be honest here, you should have MINIMUM 25K subs currently.

    Dear Tutor, or anyone knowledgeable and helpful! If the question specifically asks for the value of h, k, a, do we include the corresponding("preceding")plus / minus signs?
    Obviously I know the plus sign only would be implied, but am I right that the minus signs actually belong to the values when answering the question?

    • @TheGCSEMathsTutor
      @TheGCSEMathsTutor  4 роки тому +3

      Warrington Wolves Perfect!!!! Great start getting yourself organised, I would start with the crossover playlist here: ua-cam.com/play/PLqxP5EuGxPnfJMFKejO1mR00HafmzKW6P.html watch the first video for an overview of all of the included topics, it’s a long one but should save you hours on topics that you are already comfortable with, once you are happy with everything on that playlist you can move onto the 6-9 playlist here: ua-cam.com/play/PLqxP5EuGxPncabt7LxLs_KYkM_4Yf02cF.html and just repeat the process!! Some you might be able to skip through pretty quickly it’s all about identifying the bits you’re not as comfortable with and making them a focal point and repeat and revisit until you are happy with them! 😁🙏🏼🙏🏼
