About the Course

The course is dedicated to studying the main theoretical concepts of algebra and their application to solving various types of tasks that occur in different fields of mathematics. The theoretical part of the course includes basic concepts of algebra, including rational and irrational polynomials, modulus, powers and logarithms, trigonometry, plane and analytic geometry. The practical part of the course includes examples of tasks corresponding to these themes, as well as the methods and techniques used to solve them. This knowledge and skills allow students to start successfully the university course in calculus.

The online course is developed for use in distance and blended learning.


  • The study of basic concepts of algebra, including rational and irrational polynomials, modulus, powers and logarithms, trigonometric functions, plane and analytic geometry, progressions and vector operations.
  • Formation of the ability to solve the most widespread types of problems related to these concepts.

Information about attestation

For the attestation, the student should:

  • pass entry quiz (10% of the final grade);
  • pass control tests for the course modules (50% of the final grade);
  • complete lesson training tasks (10% of the final grade);
  • pass examination testing (30% of the final mark).

Rating system

The results of tests and completed assignments are evaluated according to the rating system, the total amount of accrued interest for all types of activities is converted into an assessment on a four-point scale:

  • «excellent» – at least 90% of successfully performed;
  • «good» – at least 70%, less than 90%;
  • «satisfactory» – at least 60%, less than 70%;
  • «unsatisfactory» – less than 60%.
