In 1834 Tolstoy enrolled in the Moscow Foreign Ministry State Archive as a "student", where he got his first taste of working with real historical documents. In December 1835 he completed exams (in English, French and German languages and literature, Latin, World and Russian history, and Russian statistics) at the University of Moscow for the formal 1st Grade State Bureaucrat certificate. He soon embarked on a career in the Economic Affairs and Statistics Department in Saint Petersburg. Before that, in July 1835, he had buried his uncle Aleksey Perovsky (who died in Warsaw of tuberculosis) and had become heir to his Krasny Rog estate. Also in 1835 Aleksey showed some of his new poems to Vasily Zhukovsky, who praised them. There's evidence that Pushkin also approved of the young poet's early works, giving him full moral support. Tolstoy wrote a lot, refining his technique, but wasn't eager to get published. "My first experiments were, no doubt, absurd, but at least metrically they were flawless. I went on training thus for many years, before I debuted... as a prose writer, not a poet," he remembered later.
