It's from teaching assistantships at both schools. Neither e-mail mentioned tuition so I am guessing it is not waived. I'm a bit worried that having less money would be stressful and distracting, because I'd be taking out student loans and I'd feel pressured to take on research assistantships as well for more $$$. That said, the pressure might be a good thing for building my credentials.
re: hair, I have a big head and volumnous hair so the long but shaved appeals to me because I like the look of long hair, but if I let it all grow out it makes my cranium look gigantic. Having less or no hair at the sides makes my head more vertical and balanced looking.
