region. As a child, Medvedev was intellectually curious, described by his first grade teacher Vera Smirnova as a "dreadful why-asker". After school, he would spend some time playing with his friends before hurrying home to work on his assignments. In the third grade, Medvedev studied the ten-volume Small Soviet Encyclopedia belonging to his father. In the second and third grades, he showed interest in dinosaurs and memorised primary Earth's geologic development periods, from the Archean up to the Cenozoic. In the fourth and fifth grades he demonstrated interest in chemistry, conducting elementary experiments. He was involved to some degree with sport. In grade seven, his adolescent curiosity blossomed through his relationship with Svetlana Linnik, his future wife, who was studying at the same school in a parallel class. This apparently affected Medvedev's school performance. He calls the school's final exams in 1982 a "tough period when I had to mobilize my abilities to the utmost for the first time in my life." Student years and academic career In the autumn of 1982, 17-year-old Medvedev enrolled at Leningrad State University to study law. Although he also considered studying linguistics, Medvedev later said he never regretted his choice, finding his chosen subject increasingly fascinating, stating that he was lucky "to have chosen a field that genuinely interested him and that it was really 'his thing'". Fellow students described Medvedev as a correct and diplomatic person who in debates presented his arguments firmly, without offending. During his student years, Medvedev was a fan of the English rock bands Black Sabbath, Led Zeppelin, and Deep Purple. He was also fond of sports, and participated in athletic competitions in rowing and weight-lifting. He graduated from the Leningrad State University Faculty of Law in 1987 (together with Ilya Yeliseyev, Anton Ivanov, Nikolay Vinnichenko and Konstantin Chuychenko, who later became associates). After graduating, Medvedev considered joining the prosecutor's office to become an investigator however, he took an opportunity to pursue graduate studies as the civil law chair, deciding to accept three budget-funded post-graduate students to work at the chair itself. In 1990, Medvedev defended his dissertation titled, "Problems of Realisation of Civil Juridical Personality of State Enterprise" and received his Doctor of Juridical Science (Candidate of Juridical Sciences) degree in civil law. Anatoly Sobchak, a major democratic politician of the 1980s and 1990s was one of Medvedev's professors at the university. In 1988, Medvedev joined Sobchak's team
