Yanovskaya/Mozgov won the bronze medal at their first Junior Grand Prix event, in Gdańsk, Poland, and then gold in Tallinn, Estonia. Their placements qualified them for the Junior Grand Prix Final, where they placed second in the short dance, third in the free, and took the silver medal ahead of Alexandra Stepanova / Ivan Bukin. After winning the gold medal at the 2012 Winter Youth Olympics, they placed fourth at the 2012 Russian Junior Championships. At the 2012 World Junior Championships, they were third in the short dance. During the free dance the referee stopped their music because Mozgov's left bootstrap had come loose. Yanovskaya/Mozgov finished fourth overall behind American ice dancers Alexandra Aldridge / Daniel Eaton who moved up the rankings and took the bronze medal.
