The present study aims at finding predictors of study habits and the ways of influence. This review work is based on 100 research papers from digital resources. It is found that all predictors of study habits can be broadly categorized as psychological, social and institution. Psychological predictors are very much proximal to students’ cognitive process including their motivation, intelligence; sociological predictors are, though distal influence the student study habits via parental expectation, encouragement and psycho-social support; institutional climate, teachers’ personality and methods of teaching and peer group influence.
