The lectures were incredibly informative. The instructor provided tips throughout the lecture on his style and skills, so I gradually gained valuable insights. The explanations were varied, so any questions I might have had were quickly answered. Why? -> The explanations, pros and cons, and numerous examples... It was the best. I gained more than I paid for, and I could tell you put a lot of effort into the PPT presentation! Thank you.

The instructor's overly (perhaps?) humble nature and the lecture content, which oozes depth, are impressive. It was great to be able to cover all the essential development knowledge in one lecture . While it might be challenging as a lecturer, I've been hoping for a series that explores the concept of developing hypothetical requirements that are both practical and essential. Thank you.

I discovered the joy of Kotlin thanks to the instructor! Although it's just a review, I'm so grateful. It felt like I met the instructor of my life ! I don't know what the next lecture plan is, but I definitely plan to take it when it comes out!

As other reviews have mentioned, the lectures are easy to understand. But the best part is that the instructors are incredibly thorough and helpful when you ask questions. For example, even simple questions like this ... moved!
