    Why can't every teacher/lesson be like this? Taking notes from this video while watching it for the first time and then recapping in my head really helps and i found is the best way to revise for me. Thanks for the great videos!

    1 day= 1 bio, 1 chem and 1 phys
    there are around 110 topics for each science
    3 videos x 60 days= triple science spec completed

    Hi, I just wanted to ask how I should use your videos for revision. I am in year 11 (doing the new 9-1 spec) and I am a triple science student. We received CGP revision guides for biology, chemistry and physics last year and I find them helpful. If aiming for top 8-9 grades, what would be the best for science revision? How are we meant to use your videos?

      It causes problems such as making you lose stamina quickly and increasing your chances of passing out of you do to much exercise because there is not enough oxygen going through your body also you colour might start going pale because you feel to ill
