I'm a computer engineering major and I started studying Unreal properly for the first time after graduating and using Unity a few times for game development contests during my undergraduate years! Most game development lectures simply follow the code or lack detailed explanations of Unreal's structure, so I had a hard time googling every day.ㅠㅠ However, Professor Lee Deuk-woo's lectures explain everything from the basics of Unreal's structure, so they were really helpful and high-quality lectures! However, I felt that it might be difficult to understand if you don't have basic CS knowledge, but for those who majored in it or have even a little development experience, I think it's the best lecture! :)
