Multiple-choice tests in pharmacology were carried out with students who had no previous experience in this kind of examination. The curriculum in pharmacology was divided into four parts. Each part was followed by a test consisting of 90 questions. A special arrangement was made for those students who voluntarily participated in all four tests during academic year. Pass marks in all four completed tests were considered equivalent to a successful outcome in the one oral examination which is, at present, obligatory. In order to encourage a high level of participation amongst the students, failure in one or more of the tests had no adverse consequences. As a result, a markedly increased attendance at lectures, as well as a positive feed back of information for the faculty, were ascertained and assessment of the efficiency of the teaching methods facilitated. Application of multiple choice tests to the teaching of Pharmacology to undergraduate students proved to be recommendable, both as a test procedure and of advantage in the actual learning process.
