How to do well in this course
Like so many formal subjects, such as mathematics, physics, biology, etc., logic requires careful attention to the definitions of terms. Every correct answer will follow from the correct definition(s) of the term(s) involved and basic reasoning skills which you bring with you to a logic class (such as the process of elimination). Also note that the logical meanings of many terms will be different than the meanings of those same terms outside of logic! This signifies that if you think you know what a term means, it is a good idea to always check to see if your meaning is exactly the same of the one given in the reading.
WARNING: the previous paragraph should be taken seriously - most errors in logic can be traced back to the student not recalling the precise definition of a term, and defaulting to some 'vague' meaning of the term they acquired before the course.
Logic is also a subject that must be learned actively, with penciled and paper in hand to attempt to reason through the questions given in the body of the text, and take notes on points that you do not understand and ask questions and consider different examples until you do understand.
