I struggled in college- my parents said they would pay half of my tuition for the first two years, and then that dropped off, so I was working full time and trying to go to school full time.
It didn't end well.
I didn't want my kids to go through that, so I told them I'd pay for everything as long as they kept a B average or better. My daughter wasn't a good student and $8000 in she decided college wasn't for her. She ended up going to esthetician school on her own, got really good at skin and brow care, and opened her own business making bank
My son graduates next week, and he's maintained a 3.9 GPA for 3 years. He was able to take college courses in high school to cut a year off, so if you can do that- HIGHLY recommended. He lived at home, we didn't make him work so he could focus on school, and it seems to have paid off. We have $14K of loans left from him so we should have that taken care of in 1-2 years.
