Sessions are set to be taught so that they finish with enough time for you to travel to your next class on campus.
If you are required to change campus and do not have enough time (such as moving from Jubilee to University Park) it might be possible to swap groups. Submit a query via the timetabling page and will investigate this for you.
If you have an online session followed by an in-person session you can book a study space to take the online session in - see 'I am a student, how do I book a classroom or meeting room?'
