Either several of those positive reviews are fake, or those MBA students are functionally illiterate.
Similarly, they can read whole books very quickly, but they do so by reading just the first sentence on every page. This is what gives them the superpower of reading large technical emails, and responding to them in seconds about a completely unrelated topic.
Lesson learned: MBA's seem to value incomplete communication, and email headers over a condensed explanation of what's actually relevant.
