How can you say this?

Hi, can you tell me how I can say this.

I want to say that if I do everything more quickly, I can sleep more:

I usually wake up at 6:50. It usually takes me about twenty minutes to prepare to go to school. I have to leave at 7:15. If I do everything more quicky and get ready in ten minutes, I can wake up at 7:05 and have more ten minutes to sleep.

1) I wonder if "prepare to go to school" is correct and idiomatic? I mean getting up, washing, getting dressed, preparing books ...

2) How about "have more ten minutes to sleep"? I don't think it's true
How will you say this? Is "another ten minutes" or "ten minutes more" OK?

Thanks

1) It would be more common to hear "prepare for school" but it is ok as you have it.

2) Your hunch was right "have more ten minutes to sleep" is bad construction. To say "have ten minutes more to sleep" is much better. ;-)

Thanks.
I will say "have ten more minutes to sleep." Is this OK?
