Its been so hard to find good videos but ever since I found your videos I've been so much better in class n have been understanding my lessons much better. According to my curriculum ( Cambridge ) I still do have more content on each topic but just cus of the way you explain things so simply I just can't leave you even though I can't fully depend on these videos for my lessons. Thankyou so much I really love your videos and I wud reccoment them to anyone any day 💕

      You can’t be, it was destroyed.
      The GCE Ordinary Level (known as the O-Level) was abolished in 1987 and replaced by the General Certificate of Secondary Education (GCSE). The change was made to create a national qualification for those who wanted to leave school at 16 without attempting A-levels or pursuing a university education.

    From what I gather, acids are good at destroying hair, metals and some other organic materials, but don't work well of greases and fats, Alkaline don't damage metals but are brilliant at removing scum and fatty substances. Their chemical opposites, one takes an electron and one gives one. Hydrogen peroxide is simply water with an added oxygen atom! I've tried all sorts to unblock my drains, but nothing seems to work, should I get a bottle of pure H2O2?
