How much time does girl need to get ready?

About half an hour

Twenty five minutes on a normal day with a reasonable amount of classes. 5 minutes for toilet business, like brushing my teeth (i take showers at night) 5 minutes to change, and 5 minutes to do my hair or makeup. The remaining minutes are reserved for packing my book bag, and preparing my car (normally picking up an already made breakfast or stopping at a FastFood restaurant on my way) to class

Half hour max but usually ten minutes
