Sleep first then study or study then sleep?

<p>I get home at 3:30 then I chill out/talk to people online or whatever.. Then I have to pick up my brother at 5-5:30.. I come home and nap for an hour or two.. Three if I didn't get like any sleep the day before.. Usually closer to an hour-hour and a half.. Then I get up, wake up and eat, then I start my hw at 9:30 or 10 and stay up til its finished, then go back to sleep until 7.. </p>

<p>It has worked well so far</p>
