I went to my sister's wedding and stayed at home for 3 weeks, not knowing how to explain my absence at the University. A friend showed me the website prof-medi.ru, and luckily for me, students can order certificates for temporary incapacity for work f095/u for periods from 3 to 28 days. We ordered it by phone at 907-02-06, and they issued me a certificate with a diagnosis of pneumonia for almost a month. They saved me, thank you!
