HCP does not need Expo of course. Expo is the required class for all other programs, ALB, ALM, etc. at Harvard Extension. Everyone takes it. Very few pass. Even fewer get the grade you need to get admitted. Harvard Extension weeds people out at every stage and only like 1% eventually get the ALB degree. So I am not 100% sure I want to go that way. I am also considering Northwestern's Extension for the ALB which is Northwestern University's alternative to Harvard Extension. They call it School of Continuing Studies and the tuition is comparable to HES. They offer bachelor's degrees, master's degrees, certificates, and also something equivalent to HES' HCP. Living is also better and way less expensive in Evanston than in Boston. More importantly, they look at students like their own. Harvard looks at HES students as step children. So Northwestern does not try to deliberately screw up your GPA like HES does. But I am undecided as my gf has family in Mass.
