Description of the organization and tasks of students’ independent work

Pre-test homework (control type - test):
1. Compare calculated results of the electrical circuit to measurements and appreciate;
2. Check if the power supply system works correctly in the study mate vehicles;
3. To find out which engine management systems are used in the study mate vehicles;
4. To get acquainted with lighting and signaling devices of their vehicles.
At the end of the course, one should defend the independent work, which examines the electric scheme of a particular motor vehicle.

Criteria for Evaluating Learning Outcomes

Quality of work performance. Understanding what you have done. Ability to logically justify processes and explain the causes of errors. Ability to discuss what you have learned.
