I think it was very helpful in obtaining the CPPG certification. Since the study focuses on key keywords and problems, it seems to have significantly reduced the study time~

I really enjoyed the lecture, which went on for four hours without a break. Just like the title suggests, it was very helpful in "Understanding the Construction of Information Security Systems." Thank you.

I took this course because I saw many recommendations for it while searching online. Thanks to it, I passed! Thank you, Professional Engineer!

It was helpful!

It does not reflect the content revised in 2023. However, for areas 1 and 2, there is not much difference between before and after the revision, so it should be sufficiently helpful.

It was easy to understand, like a pinpoint lecture

Thank you for explaining the difficult content in such great detail - it's been very helpful. I think it will be a great help for obtaining certifications. It's also good for understanding personal information work beyond just certifications.

It was really helpful because you taught me so much valuable content. I'll need to listen to it several times.

You've pinpointed the key keywords well.

Communication through questions and answers is not smooth.
