Semyonova's initial international success was at the WOGA Classic in January, where she placed first on uneven bars and balance beam.
She continued her success as part of the Russian team at the Gymnix International in Montreal, scoring an exceptional 15.95 on uneven bars, blowing away the rest of the field with her world leading start value of 7.2.
In March at the Russian National Championships, she helped the Central region to victory in the team competition, won the uneven bars with 15.975 and took 3rd on beam.
Semyonova was unable to compete at the European championships in April but returned to win the uneven bars competition at the Russian Cup in July.
Semyonova's first major meet came in April with the European championships, where she helped Russia take silver in the team competition and secured gold in both the uneven bars and the balance beam, with scores of 15.9 and 15.95 respectively.
Her success continued in June when she finished 2nd at the Dutch Open, behind Anna Pavlova, the two of them leading an all Russian sweep of places first to sixth.
Semyonova had problems during the Russian Cup in July, where she fell on beam in qualifications and on vault in the all around final, but she still managed to take silver behind her teammate Afanasyeva.
Semyonova ended the season with a wrist injury that prevented her from competing at the World Cup finals in Madrid.
After a qualifying round marred by wobbles and a fall on her floor routine, she was 10th going into the all-around but failed to make any event finals.
She also performed a Deltchev salto on uneven bars, now an unusual skill in the women's sport and an uncommon piked double Arabian dismount.
