I enjoyed the class as it added to my knowledge and was organized nicely.

However, the transcripts were riddled with mistakes, worse than I've seen with any coursera course. I had some familiarity with the topic and was able to correct the translation from spoken to written but a better system needs to be installed when using a lot of very specific scientific terminology. What ever system you were using, it didn't work. I realize this course came from Korea and perhaps English was not the professor's first language but it was quite laughable to see the riducules mistakes made for words such as kinase (kindness( and binding (combined) when the professor was saying the correct term.

In addition, the quiz and exam questions were poorly written with a number of grammar mistakes making it difficult to interpret the questions.

This is not a well-prepared course. Instructor doesn't seem to be comfortable with the material (or maybe with the idea of being recorded) and just reads the slides adding very little to them. Most images are not explained or very superficially explained. They keep showing 3D structures of the various proteins for some reason - those images tell us nothing, and add no educational value to the presentation. The course is poorly organized - secondary messengers are not defined or explained until module 4 (Why?!?). This should and could be an interesting course - I hope they continue working on the content and presentation to make improvements for the future. In its current format, I feel sorry for any student who pays university-level fees to sit in that classroom.
