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😉

@TheGCSEMathsTutor 4 жыл бұрын

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.

Warrington Wolves Perfect!!!! Great start getting yourself organised, I would start with the crossover playlist here: kzfaq.info/sun/PLqxP5EuGxPnfJMFKejO1mR00HafmzKW6P 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: kzfaq.info/sun/PLqxP5EuGxPncabt7LxLs_KYkM_4Yf02cF 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! 😁🙏🏼🙏🏼
