100 logic tests with answers

Introduction

The proposed test will help in the study of logic. It can be used for self-preparation, as well as - in the control and consolidation of the main classroom material. It can also be used by teachers to conduct test and test examinations for the course of logic.

The test includes 100 tasks of the closed type, which greatly speeds up the teacher's test work. The tasks cover all sections of logic and allow not only to verify that students have the required amount of knowledge, but also to assess the level of their logical culture.

The suggested answers are structured in such a way that each of them can be chosen as an unprepared student as the right one, so the test cannot be completed formally, at random choosing the appropriate answer option. For its successful implementation requires real knowledge and skills in the course of logic. Such a construction of test tasks makes them more complex, but at the same time more interesting and greatly improves the efficiency of control of students' knowledge and skills.

When evaluating test results, you can use the following system:

NUMBER OF CORRECTLY ALLOWED JOBS
