A questionnaire (in yes or no answer format) with 20 questions on acne, each carrying one mark, was to be answered by the students. The students were categorized into 4 grades based on the marks obtained: Grade I 90% marks and above, Grade II 75%\u201390%, Grade III 50%\u201374%, and Grade IV &lt;50% marks obtained. <jats:italic>Results.<\/jats:italic> Of the 144 students of the batch, 95 (69.5%) completed both pretest and posttest questionnaires.
