  Thanks for the feedback. I will try to talk slower in future videos. I hope the test goes well.

    Thanks for this video, it helps, it would’ve helped me more if I’d remembered it in my exam, that’s the reason i’m here anyways, parents want me to answer questions I either did wrong or didn’t answer . And you aren’t going that fast. Your at a decent speed in my opinion

  What? He really doesn’t talk too fast!!! He talks slower than most people. It might not be easy to understand the maths, but it is easy to understand what he is SAYING.
