I’m a student of the Medical College
Last year I finished secondary school. My favorite subjects were chemistry and
biology. I passed successfully the Uniform State Examinations in chemistry,
biology, mathematics and the Russian language.
According to the results of the Uniform State Examinations, I was admitted to
the medical college. This medical college is a middle medical school that trains
specialists for curative medicine. Now I am a first year student. I study at the
Nursing faculty. There are day (full-time), evening (part-time) departments in mycollege. I entered the medical college because my dream is to become a nurse and
help people suffering from different diseases.
I am from Nizhni Novgorod. I live here with my family. I decided to enter the
medical college because it is one of the best middle medical schools. When I have
free time we often go to the cinema, visit exhibitions or museums or walk along
the streets of the city admiring its beauty. I also go in for sports. I play basketball.
I am very happy that I have entered the medical college. It is very interesting to
study here, though not easy.
