Mathematics entrance examination program is developed on basis of the exemplary program recommended by the Ministry of Education and Science of the Russian Federation.

**MATHEMATICS**

This program consists of three sections.** In the first section** there are listed the main mathematical concepts every applicant has to know for passing both written and oral examinations.

Extent of knowledge of the material described in the program corresponds to a high school mathematics course. Applicant may use all means from this course, including elements of calculus. But to solve examination problems it is enough to have solid knowledge of the concepts and their properties listed in the present program. Objects and facts studied at general education school also can be used by applicants, but provided that they are capable to explain them and to prove.
