For the most part, getting or finishing up towards a degree isn’t easy when working full time. Then we can add family and kids into the mix. One may have a situation where it works, the next may find it close to impossible. No one size fits all.
Now just finishing up a few classes is doable. The type of degree would factor it, and the school in question.
I hesitate to say exactly what may work or may not, some are much better at getting things done than others. One may have a supportive spouse, the next has a spouse threatening to leave if certain ‘needs’ aren’t being met.
I have flown with some taking classes towards a degree. One has to adjust around it. I’d much rather ‘finish up’ doing it while working, than doing the bulk towards a degree.
