I did access to nursing on a 2 day a week basis. I imagine the workload will be similar.
I worked the 5 days, maybe doing 30ish hours and then went to college for 2 days a week. It definitely required for me to time manage. I always stayed on a Monday night after college ended to work on assignments and was always in the library on Weds afternoons because that's what worked for me.
It is constant assignments, so you never feel relief for finishing 1 because there's always another waiting in the wings. During my course we covered 5 subjects and each 'term' had either an essay or exam to complete for each subject which were usually all due within in a week of each other. So while it seemed a lot, it definitely needed to be broken down and chipped away at.
In terms of time off, it was like being back at school in that we had half terms, xmas and easter off. I started my course beginning of Oct and finished it beginning of June.
The complete amazing flipside is it 100% prepared me for Uni in terms of writing style, referencing and time management. Plus, if you can handle the workload of an access course, you can handle Uni. I'm about to finish 1st year of nursing and found the workload of the access course much more challenging. I've heard that changes going forward into the next 2years though, haha.
