Time management

I am currently living in Leicester and after college I go mosque at 5 o'clock, during the week. Is necessary for me because I am doing a course to become a scholar.
The thing that I find difficult is being the timetable extended till 6 o'clock and it will take me 30/35 min to reach the campus or more than that.
My question is if I want to change my timetable and make it till 4 o'clock everyday for a relevant issue,is that possible?
