which one is better?

salam, give me your opinion.

Package A

studying untill late night, burning midnight oil till 3am @ till subuh prayer-at 4.20am and getting earlier.

Then after performing solah, and Al Mathurat(if I not fall asleep) go to sleep until 6.30 @ 7am and get ready to go to school(university)
Sometime @always I'll sleep after asar to compensate.
As I'm practicing this, I have more time n focus to study.

Package B

Early sleep, after isya-at 9.20 and getting more late. And some revision for todays' lecture, go to sleep about at 10pm, and wake up at 2am for study.
Some nap on the evening.
As I'm practicing this, a little bit sleepy, and lost of focus.

thanks
