The instructor is handsome.

The content of the material is slightly inaccurate, and considering there are no past exam questions, 38,000 won feels like a waste of money.

The materials are very helpful.

The quality is incredible for a free lecture. I'm a high school senior starting out in digital forensics, and I've learned a lot.

The content seems well-condensed, but the document editing feels so haphazard that it's difficult to read... I wish things like tables being cut off or just one or two lines spilling over to the next page could be fixed so that it's easier to read at a glance, even if it means leaving empty space and wasting paper. Right now, it just feels like a set of handwritten lecture notes passed down in college. I wonder if this is really worth paying over 30,000 won for.

This is a very helpful lecture. Thank you. ~

I was reading "Digital Forensic Technology" (Korea Forensic Society) after purchasing it, and I want to thank you for organizing the content so well that I could study the missing pieces quickly and easily. I am currently preparing for the Digital Forensic Level 2 certification; although I’ve read the book many times, I felt lost regarding how to prepare and which specific legal areas to study. Thank you so much.

It was very helpful!

Can't I get past exam questions?

Thank you for the good lecture.
