I question if these guidelines mean anything. My strategy, if I had a degree from Harvard (or associated, in this case), I would be to put "I have a degree from Harvard" & a Harvard logo on the resume, plus some level of indirection to make it look less blunt.
Harvard-educated students are possibly the pool of people with the least competitive pressure to come up with a good resume.
Go find a management consultant with 10 years experience and ask them for advice to get a good resume written. It won't look like this.
Wondering why you think like this? Harvard has 12 schools, extension being one of them. They all grant a Harvard degree. I've been very pleased with it, very challenging course work. Several of those courses shared with what you consider "real" Harvard students, the only difference being they had to be in person at the lecture hall.
