I'm sorry, but youtubers make this material much easier than any teacher I've ever had. The hard part is just knowing what formulas to associate with the jargon, and these clear that up easily.
Thanks so much for putting up these tutorials. Without them I wouldn't have got this I don't think! Very clear, concise and well taught. Well done and thank you. I just wish more tutors in schools knew how to teach.
