In this part of the course, students acquire practical skills by working in the laboratory and based on the knowledge gained in the first part of the course. Students strengthen their knowledge of the taxonomic diversity of the animal kingdom, plans of the body structure of animals of different systematic groups, life cycles of parasites
knowledge on body plans and physiological processes of animals of different taxonomic groups; on diversity of the kingdom of animals and on the structural adaptations and life cycles of parasitic animals. 4 Colloquiums
• skills to work with microscopes and to evaluate microscopic slides, to carry out dissections of animals, to search for zoological and ecological information and to analyze it. 4 Colloquium
• competence to evaluate the importance of wild animals in the protection of animal and public health and in the protection of environment, to be competent and to be able to find information on the taxonomic status of different animal species. Exam

Each student must participate in at least one field trip during the semester. The teaching staff offers the topics and times of the excursions to the students at the beginning of the semester. 8 h
At the end of this part of study course students are evaluated by exam. To get the examination grade students must have positive results in all tests of the first part of the course in autumn semester, to have participated in all laboratory works, have passed all four laboratory tests, have to participated at least at one excursion and have to submit a report after the excursion.
The students have the rights to pass the laboratory tests if the student has participated in all laboratory worksand the results are accepted by teacher. In a case, if the test result is negative, it must be repeated later. Students have to prepare a report after the excursion they have participated in. The report must be approved by the teacher.
The laboratory works have to be defended and accepted by teacher. During semester four tests have to be passed. The test is evaluated with 1-5 points. The total number of points is calculated as the sum of points of all four tests multiplied by factor „3”. Thus the minimum number of points is 12 (1x4x3) and the maximum number of points is 60 (5x4x3). The number of points the student received at the end of first semester is added to the number of points received during the second semester. The exam grade is calculated according to the total amount of points:
79-100 (points) – 4 (grade)
101-115 – 5
116-130 – 6
131-145 – 7
146-160 – 8
161-200 – 9
