My teaching videos do exactly that, teach you a topic from scratch. These videos are especially helpful if you have missed a topic at school/college and reading up via a text book isn't enough. Maybe you just didn't understand the lesson in class? Hearing a different explanation can often work. Maybe you're an independent student and are studying Chemistry in your own time? I've had lots of messages from students who have done just that and used my videos to help them succeed.
I have organised the videos by typical year of study (year 1 and year 2) and then by module and topic
