I found the class to be very detailed and informative.
Content is ok, but she reads off the slides almost verbatim which is distracting and unhelpful. It would be better if there were fewer words on each slide. I'mn sure this isn't the case, but I get the impression that she doesn't have a solid grasp of the content, hence the slide reading line by line.
