Good

I really enjoyed the lecture!

It's easy to understand. For your information, "개수" is the correct spelling.

This seems to be the most appropriate course for studying Kotlin Android development for the first time. When you don't know what to do in Android development at first, watching this course and getting familiar with Android development will be very helpful for future learning.

You explained it in an easy-to-understand way

It seems like you summarized just the key points, so it was good to read.

This seems like a good lecture for people who already know the basics and want to refresh their memory, rather than for beginners like me. I'll think of it as a preview and listen to the lecture. Thank you.

Thank you for the great lecture!

Overall, it's concise but provides good explanations for the necessary parts. It's a great lecture for quickly reviewing concepts that were confusing or unfamiliar. I think it's a good lecture for checking your own development knowledge.

I understand very well. Thank you~
