I am a junior and freshman and sophomore year i did AWFUL. i was very medically sick with seizures and recently have gotten brain surgery and have been seizure free for 3 months! all grades r A and B this year… i have 250 community servicwe hours, I am in 5 clubs , BBYO, Buddies (where we play sports w special kids), juniorettes (community service), spoken word (i am a very very very big writer…) ,writing is one of my favrotie things to do, i am on the school spoken word team. i play tennis , and the classes i take ths year are chemistry 1, english 3, us histiry hon, creative writing hon, algebra 2, peer counseling, and teaching assistiant. i would be in honors and AP if i didnt go through missing so much school for my medical issues which made my life so hard. i take the ACT in febuary, iM just nervous, NYU has been my dream school since before 5th grade when my seizures began. I have a 3.2 unweighted gpa. it couldve been soooo much better if i wasnt sick for these years. I wanna go to NYU for journalism.i just dont know if there only gonna look at grades. and im really nervous. do you think my essay can help and all of the othe things?
