3 hours ,because studying too much at a time can make you forget earlier.
I think a student should study minimum 6 hours for each day but it depends on the calibre of student if the learner is slow, he should work more than 10 hours if he is quick learner than 6 hours are enough.
It depends on a number of factors, such as: year of studies, workload, curriculum, student's needs, teacher's demands, exams in sight, Thesis, etc. In general, a student is very busy all 7 days a week, morning thru evening
