The test is 100 questions about 15 on early years, 15 on Lenin years, 30 on Stalin years, 6 on Khrushchev, 2 on Brezhnev, and 10 Gorbachev.

I used:

Wikipedia Soviet Union/History
J 947.08 Ing Russia and the USSR, 1905-1991 (Children’s book but highlights many key points)
321.9 Mal The Soviet Tragedy: A History of Socialism in Russia, 1917-1991 (Excellent book but I only made it to 120 pages)

This was good enough for… I tell you when I get my grade..

They asked for a couple of famous Russian authors and defectors not mentioned in my studying.

I don't remember any question predating 1898 about Georgi exept for one about Alexander III mentioned above.

Also some other key notes…

Khrushchev prevailed, becoming party leader on September 7 of that year, and his main rival, NKVD chief Lavrenty Beria, was executed in December. Know the other names? (if any)

June 22 - World War II: Germany attacks the Soviet Union in Operation Barbarossa

Leonid Brezhnev established himself in the early 1970s as the preeminent figure in Soviet political life. Brezhnev presided over a period of Détente with the West while at the same time building up Soviet military strength; the arms buildup contributed to the demise of Détente in the late 1970s. Another contributing factor was the Soviet invasion of Afghanistan in December 1979.

Mikhail Gorbachev made significant changes in the economy (see Perestroika) and the party leadership. His policy of glasnost freed public access to information after decades of government regulations.

Know the dates each person ruled from and to… this will help keep a time frame in mind. I don’t recall on actually question on it.
