The word 'Logic' is derived from the Greek noun 'logos' meaning both 'thought' and 'the word expressing thought'. Thus, LOGIC is the ‘science of thought as expressed in language’. This means that the questions on logic are to be solved as per the information given without any concern of the formal validity or truth of the statements i.e. conclusion should follow directly from the statements given. With this unique characteristic, the Logic Test becomes an instrument of teaching the candidates to follow the rules and work as per the instructions without an error. Thus, it prepares the mind for all types of reasoning practices and teaches how to detect and avoid mistakes in the same.
