It's been about 2 hours now? I've listened to the lecture, and it's easy to listen to because it progresses step by step from the basics. There's no break in the flow while listening to the lecture, and I don't know if the code entry part is fast or if it's done at the speed, but it's done in an instant, so it's easy to continue the flow. There are simple quizzes in between, so you can write SQL yourself and use what you just learned, or there are quizzes that require you to learn later, and thanks to this, you can learn why you need to learn later, which is good.
