I am sharing my personal views from a learner's perspective. I hope this helps those who are considering taking this course. 1. The system flow is easy to understand. In each lecture, the instructor explains the system flow of the feature being implemented using various materials. Since the visual aids change according to the flow, it’s great because you can visualize difficult concepts before diving in. Since architecture is more important than code implementation, this is a truly excellent element. 2. It covers concepts. Because the concepts are covered, it’s easy to understand and you learn the "why" behind things. As I gained knowledge this way, I personally became curious about how the instructor studied. It made me think that the difference ultimately lies in how deep one digs into official documentation and references; it challenged me to realize the importance of looking into the source code and acquiring knowledge "also" through official documentation. This isn't just a simple clone coding course. 3. It’s not just "easy." While the concepts are explained well, it’s not incredibly easy. As it is a practical project, the important parts have some level of difficulty. Personally, the difficulty level was just right for me. It’s perfect because it’s neither too hard nor too easy. 4. Diction The instructor's diction is very good. They say you notice the difference most when it's gone. I didn't necessarily feel that good diction made me focus better, but it's very difficult when the opposite is true. There is absolutely no such stress here. ** Conclusion ** I think this course will be helpful for those who want to get a grasp of the project flow. I had experience implementing parts here and there, but I realized that knowing the architecture and system flow that make up a project is what's truly important. Those who haven't experienced a project from A to Z will receive a lot of help from this.
