Once back home, Kim Jong-un attended Kim Il-sung University, an officer training school in the capital of Pyongyang. Kim Jong-un obtained two degrees before he graduated in 2007: one in physics and another as an Army officer through the military branch of the school. In 2010, he was publically introduced to the North Korean people and his identity was fully revealed. This was also the year when he officially became a member of the Worker's Party of North Korea.
