    maths has always been stressful but after actually revising for once and using your videos everything is much easier to understand. thanks a lot for these videos man. quick question though, where would the foundation only questions end? since i'm not doing any higher papers.

      Amazing news I’m so glad it working for you! So great to hear that everything is seeming easier and that you are gaining confidence! With my videos, if they are titles as “higher and foundation” or grade 5, these are topics that appear on both papers so the whole video is applicable to foundation as well as higher 😁🙏🏼
