Harvard may once have been the sole realm of US Royals, such as the JFK and his family who spoke found of "Hah-vad." No more! The welcome mat is at least tenuously tossed onto the stoop for the rest of us. There are 348 online courses which do not require official acceptance, many at no charge or low charge.
I enrolled in the Harvard Computer Science for Lawyers class. There is no charge for auditing the class. For verified certification, there is a $199 charge.
In a lighter vein however, there are cooking, art, music, all sorts of options! If you're feeling a bit stale from too much remote work and Netflix is losing its luster, may be some learning will refresh and renew!
