Do you loose childcare element of working tax credit if you become a university student?

[Avacathar]

So up until 3 days ago I was going to university in Brighton, but I just found out I have a place at Exeter university; which is in driving distance of my home. I currently work 16 hours alongside my diploma, but after looking at Student Finance am i correct in assuming you can only have one or the other? I will definitely pick a place at Exeter over my 16 hour job, but it would be nice if I could still do both. Anyone have any knowledge on university finance for single parents? thanks all :)
