I have listened well to your explanation regarding the essence and philosophy of object-orientation.

Thanks for the materials.

I was planning to try making an app with ads as a side project, and I was able to create one just by following along. Thanks to you, I'll try to make some great apps in the future!

There weren't enough past exam questions available on the market, so I did extra studying with the 500 questions provided here, and thanks to that, I passed! Thank you! While the concept book was a bit lacking, the past exam questions were great.

It was great to be able to learn C++ and Java at the same time, and I also loved being able to learn object-oriented programming. Furthermore, it was very beneficial that the lectures integrated object-oriented concepts with Computer Science.

It was great because I could thoroughly study all the UML diagrams, including the syntax and how to draw them.

The guide on how to use prompts is great.

I lacked a lot of the basics, but after taking this course, I was able to build a solid foundation.

It was great to be able to learn everything up to object-oriented programming while comparing C++ and Java, and this lecture completely cleared up the structural differences that always confused me. In particular, the parts explaining the virtual table, JVM memory structure, and the internal workings of polymorphism from a comparative perspective were truly impressive. It’s not just a simple syntax lecture, but one that helps you understand "why it was designed this way." I highly recommend it to anyone who wants to explain object-oriented programming with confidence in interviews.

It was good to learn how to approach the defense industry. Overall, I was satisfied, but it felt a bit lacking in specifics and somewhat repetitive. Still, looking at the big picture, it was very helpful.
