Describe a significant challenge you have faced and the steps you have taken to overcome this challenge. What did you learn? How has this challenge affected your academic achievement (400-500 words)
would not let me put 400 or 500 words in boxes above.
i can’t really think of anything for this. i wrote the below but am up for  suggestions…. lol
i’m bad about not going to bed early. i stay up late studying and then i’m exhausted when i get up. it hasn’t effected my grades academically.
putting myself on a more organized schedule – trying to go to bed at or before 11:30pm, gives me about 8 hours of sleep before i have to wake up and get ready for school at 7:30. i’ve tried to keep myself on this schedule even on weekends although sometimes i do sleep late. i’m just naturally a night owl, but also makes me not a morning person.
getting on a schedule i think this has helped me to be more rested and focused during school hours and has possibly helped me make better scores on tests than i might have normally would.
