I was fortunate to have a flexible job in administration. I was doing about 32 hours a week ( 4 days a week ), then part time college, 6pm - 10pm on Tuesdays and Thursdays, then 9am - 6pm on Saturdays, started when I was 30, graduated this year. I was able to keep this going for the whole 4 years in college and graduated with decent grades too. It was still exhausting, no free time since my free time was being spent working on college assignments. Not sure how folks who do both full time work and college manage.
It helps a lot to have a somewhat flexible job, and a supportive partner.
You can just turn on light mode you know.
