    honestly, I have tried private tutors, school tuitions, extra classes and none of that helped until when I watched this video. You are absolutely amazing and my entire batch is very grateful for you. The world needs more people like you! Please keep doing what you do.

      @@ObeyGoodness_20 Just fyi, "I can't love you LESS" means that you love them so little that it's impossible to love them any less than you already do. I think you meant, "I can't love you MORE"...? :-)

    This is not generally requested and so it has been left out so far in my videos but I understand your point. A video on this will take me as always approx 3-4 hours to develop, produce and upload. If you wish to make a donation of £30 at least then I am happy to do this for you. Sorry to make a charge but I hope you understand.
