Completing Homework= Not Sleeping

So I stayed up until 4:30 this morning to try and complete my chem ISU, all I needed to do was summarize all the notes for one chapter and finish the assigned questions. I almost finished the notes over the break, with two left. So I finished half of one note before I got bored and decided to do some of my law on the computer. 3 hours later I was almost done my law, had eaten supper and had barely looked back at my chem. By 8:00 I realized I had to start working on my chem because of course its due the following day. So from 8:00-4:30 I worked on completing my chem homework, with a short break every couple hours. By the time I was done, almost all, skipped like 5 questions from the entire unit, 'cause I didn't understand them and it was getting late. So finally I get to go to sleep and about an hour and half after I fell asleep my mom woke me up to go to school. By this point I was super tired because I was up late the night before finishing a Bio project due a day earlier than what I thought it was. So I'm beyond tired and was so slow getting ready for school the I missed the bus again. But I was allowed to stay home due to being sick from lack of sleep. So tomorrow I have to hand in my assignent and right the test on the unit. Luckily the date for my law ISU presentation was moved to Monday rather than Friday, because I have a bio paper due Friday, and a chem unit test. Getting late gonna slepp finally.
