Okay, there are flashcards I made from information I got from Wikipedia attached. Also, there is a brief timeline provided at
Timeline: USSR that was helpful.
As for events you need to know...
-The Revolution of 1917
-The Russian Civil War
-The different parties that formed during the revolutionary period
-The Soviet Union's relationship with the rest of the world during the World Wars
-Collectivization
-The Purges
-The decisive battles during WWII for the USSR
-The starting and ending points of WWI and WWII
-You should also keep in mind all of the rulers of the USSR and when their reigned. For Example, after the revolution it was Lenin, Stalin, Khrushchev, Brezhnev, Andropov, Chernenko, and finally Gorbachov.
-You should also know how and why the ruler's ended their reign. For Example, what was the main reason Khrushchev was ousted?
-Also, how did the USSR handle the Chernobyl Crisis.
-One final note-and this is something I wish I would of been stronger in-you need to know which satellite states wanted indepedence, got independence, didn't get it, and who joined the new government at the end of the USSR and who didn't.
This is an upper-level as you know, and so there is A LOT more information packed into it than most of the lower-level courses. I don't know about anybody here, but I started prep for this test blank, meaning, I didn't have any schema or familiarity...and I still passed.
I hope this was helpful.
