So i'm about to start a job at paper delivery at the local newspaper company and i have to wake up at 3am and start the job. the only problem for me about this is that i'm attending college and so i dont think i'll be able to sleep at like 8 or 9pm since i'll need time to do homework and stuff. i was considering staying at my current job (which if i still do school + current job, i'll finish at 10:30pm) and still doing paper delivery.

so i made my schedule with all possible outcomes:
1) winter session
sleep time: 3.5 hours, 4 hour nap
work time: 2 hours, 5 hours
freetime (including hw): 3 hours (9 if i quit current job)
total monthly pay:~$1300

2)winter session (without paper job)
sleep time: 6.5-8.5 hours
work time: 5.5 hours
freetime : 4 hours
monthly:$~600

3) spring semester (february - june)
sleep time: 4 hours, 3 hour nap
work time: 2 hours, 5 hours
free time: 2 hours (8 if i quit current job)
total monthly:$~1400

4) spring semester (without paper job)
sleep time: 7.5 hours
work time: 5.5 hours
free time: 2.5 MWF, 6 hours TTh
$: 700

which of the four options would be best? can i survive sleeping short and taking a short nap before school, or am i way better off sleeping straight?
