I need some new hair styles for school!?

I get up at 6:30 every morning. I usually straighten my hair with a CHI flat iron. That's it. I wear my hair straight and down. No Clips. I need new hair styles I can do quickly in the morning. I've tried to curl my hair with four different curling irons and tons of hot rollers. My hair DOES NOT curl. At all. I need some major help.
