Hi Ravi. Usually, the timmings for an undergraduate degree/course, the timmings for a college remain from 9am to 5pm with breaks in between the studying hours. And the college is usually from 9am to 5 pm from monday to friday. Some Colleges give an off on Saturdays and sundays, while a few run institutions on Saturdays as well ( from 9 am to 3pm/5pm).

I hope this information has helped you :)
