help?

Okay serious question, any tips on how to get my work done and maintain a healthy sleeping schedule? In 9th grade I want to apply for my county's Institute of Technology for a year, but to do so I need to have good grades, and I really want to get myself together since the earlier I start the habit the better (plus my mom will prolly stop yelling at me). It's mostly HW problems plus lack of a good sleep schedule (I tend to have trouble staying awake the first 3 periods of school, which sucks especially since Geometry's first period), so yeah, any tips on that?
