Is it not good to wake up at 4am and go to bed at 11pm?

I am a university student who even though I have online classes I still have to get up early to get everything done in a day. I tend to either have classes or work between 8:30 am and 3:30pm 7 days a week so the only time I have to get what I need done in the day for study, workouts and chores around the house is either early in the morning or right after work/school. If I do not have to go out and run arrens then I will usually do house cleaning work and other non school or work work in the mornings from 6am to 9am. I do normally workout after school/work and before dinner from about 3:30pm or 4pm to about 6pm. The thing is that I tend do at least min once a week of a morning workout insead of an afternoon workout so that I can get groceries and what not I need while the stores are open. my evenings after dinner are most days of the week my only time I have to get study and homework done if I do not have free time to do it between classes. Here is a ruff schedule.

5:30 breakfast 

6am chores, homework, or workout

9am class or work

3:30 workout or arrens

6:30 Dinner

7:30 Study/Homework

10:30 Bedtime
