I am a current OMS-I at ACOM and my class is very active on Facebook. We have a private page for our class and that page has become a huge study aid. People are always posting vignettes, study guides, flashcards, etc. It is also a great way for our class to keep in touch and send out reminders about classes, school events, and if we actually need to wear our white coat today
. There are people in the class with Snapchat but it is more "social" than our class Facebook page. (Though there are at least 2 good memes posted daily).
I know that the c/o 2020 has a Facebook page started already and that there are current students on there right now as well to help out and answer questions but once classes get going the current 1st, 2nd and 3rd years will leave the group and let it become strictly 2020.
If you have any other question feel free to PM me!
