I was totally burned out by uni in my second year, but third year ended up being amazing.
I preferred the wide range of choice we had in modules, and the independence of pursuing my own research for the dissertation.
Also, contact hours were minimal in third year, so I was only on campus 2 days a week, for two 12-week blocks.
I'm not sure if his previous experience was pastoral (outdoors, in nature) or pastoral care (support work), but having the degree will give him the option to pursue postgraduate conversion courses in either area.
He could always use a DipHE to build towards another qualification at a later date, but those I know who have taken this path have found it harder.
It's easier to pursue education when you have a cohort around you. When you and/or your friends are all working, in relationships and have kids, studying can feel lonely.
