Introduction to Logic Test 02

This test has been designed to assess your comprehension of the Introduction to Logic Lectures by Dr. Leonard Peikoff. Questions have been formed from lecture 2 only (Discs 4-6). There are 25 questions - each is worth 4 points. This test can be taken by students before and after listening to the lectures (as a pre and/or post-test). Only reading Ayn Rand's fictional work will not be sufficient preparation to excel on this test. This assessment can help students of Objectivism and study-group organizers determine the ideal study materials and is not intended to evaluate one's agreement with Objectivism.

Note: All questions are formed from assertions and arguments made by the author of the material. When answering test questions, please keep in mind that the "correct" answer is based on those assertions. The Culture of Reason Center does not necessarily endorse the positions articulated in the subject material.

Test Score Range:
0-60: Minimal understanding (Low) - Basic study needed
61-70: Moderate understanding (Low-Mid) - Basic study needed
71-80: Good understanding (Intermediate) - Basic study review needed
81-90: Competent (High-Mid) - Proceed to more technical studies
91-100: Advanced  (High) - Proceed to more technical studies

In order to receive your test score, you will be asked to provide your name and email address. Your test score will be emailed to you. Your name and email address will be added to our general contact mailing list. Your name and test scores will not be published. All marketing emails sent from The Culture of Reason Center include the option to unsubscribe.
