FORMS OF CONTROL

When students study subjects three types of control are provided for: current, modular and final.

• Current control is at carried out in classes in the form of oral responses to test questions after each work. The current control is also used regarding to the fulfillment of original work in the form of oral answers to test questions on the topic. A student can score maximum 40 points (20 points in each module) for current work during the term.

• Modular control is carried out in reference to lecture course in the form of modular examinations following completion of each of 2 modules by written answers to test questions on the module. A student can score maximum 60 points (30 points in each module) for modular tests during the term

• The mark on the subject is presented as arithmetic sum of points, scored for the current work for 2 modules, and points scored for two modular tests. Thus during the semester a student can score maximum 100 points (50 points per module). When the student is satisfied with the scored amount of points, the procedure of final control is only summation of these points.

• Final control in the form of credit is carried out provided the student has passed all stages of current and modular control not scored the required number of points for the credit (less than 60) or when the student aspires to highest rating. The opportunity to give written answers to total test questions. In this case evaluation of the subject is presented as the arithmetic sum of points, scored for the currat work for 2 modules, and points scored at the final control (maximum 100 points). In this case points scored at modular control are cancelled.
