The immediate passing of an exam or test in any academic discipline is always preceded by a fairly short period when the student must concentrate and systematize his knowledge. In computer parlance, it must “move information from long-term memory into working memory,” making it ready for immediate and efficient use. The specificity of the period of preparation for an exam or test is that the student no longer studies anything (there is simply no time for this): he only remembers and systematizes what he has learned. The proposed manual will help students in solving this particular problem in relation to the course “Ecology”. Contents and the structure of the manual meets the requirements of the State educational standard for higher professional education. The publication is intended for students of higher educational institutions.
