Study habits are the most important predictor of academic performance and global research has revealed that study habits affect academic performance. In this regard, Nursing students are faced with a large amount of information that is difficult to organize and learn, which requires not only knowledge but also the application of study skills. The main objective of the study was to evaluate the effectiveness of study skills on academic performance among nursing students. A pre-experimental research approach, group pre-test, and post-test research design were adopted. The data was collected from 78 students of I year B.Sc Nursing (2019 batch) of PSG College of Nursing, Coimbatore. The tool comprised of Demographic variables, VARK Questionnaire (version 7.8), and Study skills questionnaire. Assessment of Learning styles indicates that in total, 58 students (76%) preferred only one learning style (single modal), and 18 students preferred to use multiple learning styles (multimodal). The statistical student's test was computed between pre-test and post-test mean scores of Academic performance. The calculated was 35.93, which was greater than the tabulated value (3.195) at p<0.001 level. The results clearly stated that there was an improvement in academic performance of first-year B.Sc. Nursing students after the understanding of study habits.
