I noticed some places in the Google Web Accessibility Course where the caption text does not match what the speaker is saying. I took a screen snapshot of each place that I noticed. Please note that the time stamp (embedded in the file name) for each snapshot is approximate.
I'm not sure how to report these issues, so I hope that this feedback makes it to the right person.
By the way, I think that this course is excellent, which is why I went to some effort to provide this feedback to improve it for future students. :)
