This is a great lecture for someone who doesn't know anything about spring and is just starting out!! I listened to it because it was recommended to me, and it seems like a good class!! I like how it explains everything step by step, one by one! In particular, since it teaches you how to repeat things one by one, not using shortcuts or copy and paste, I think it's a good learning method that I can remember more! The only regret is that I personally made additional sounds (salty!) with my mouth, so I was concerned at first, but the content was so good that I was less concerned as I went on!
