I didn't study or do homework in high school. Graduated number 3 in my class because my principal thought someone who doesn't do homework shouldn't be salutatorian. In college my friends REFUSED to take classes was with me. Called me the "curve wrecker." Anyways, just do your best. High school doesn't matter once you get out. Hell the friends won't even matter. If you're passing you're passing, the letter grade does not define who you are as a person. Also, use YouTube for your struggling classes. Don't let high school dictate your life.
