Honestly you can. If you take one or two classes at the time while working full time and you take like 20 years to finish. And forget about a gradaute degrees because most of the time they're are full time programs.
Wrong on the graduate portion. My Dad worked on his doctorate part time and in the tech industry it is fairly common for people to work full time, while also working on their graduate degree on the side.
I think he/she is referring to the course load not being full time. Not working. You have to work full time to pay for part time classes. But grad programs require full time classes (and often full time work)
if you notice, I didn't say all graduate degrees are full time.. Some you could do part time and are designed for full timec withers only meeting on some weekends. But a lot of them are film time programs, actually in these medical field. Also, even part tine programs are hard to afford and most people either do it slower than part time or take advantage of some kind of compensation from work for education.
There are some types of grad degrees that don't require full time commitment to courses. My roommate in vet school is working, she has in internship, but it frankly isn't possible for her to make enough at her job, though she works ALL THE TIME including christmas day, to pay for vet school. My dad's MBA program though, he works full time and has enough time for courses. You can't always be a part time student in grad school, but it is possible in some instances. For the MFA I'm applying for, there are some schools that offer a part time program over 5ish years, and some that will knock it out in 2ish years.
I paid for my first degree, 20 years ago by working and paying as I went along. It was difficult but affordable. I had to take out loans for my second (8 years ago) degree. I will be paying on that until I die... despite earning 3 times the annual salary I did during the first.
