So I’m rather worried about my grades. Most of my grades are rather border line and worst case scenario I am ending with 3Bs my sophomore year. How badly will this hurt my chances into college? I am hoping to get into my state school’s honors program but my dream schools are Georgetown, Navy, Swarthmore, and Columbia U.

My grades freshman year:
Geo Honors: C
LA: A
Bio Hon: A
World His Hon: A
Gym: A
Choir: A
Spanish 3: A
Gpa: 3.7
WGpa: 4.2

Sophomore (best grades possible)
LA 4 Hon: A
Chem Hon:A
Adv Alg: A
Spanish 4 Hon: B
American History Honors: A
Gym: A
Choir: A

Sophomore (worst grades possible)
LA 4 Hon: B

ECs:
-Lead in Fall Drama for past two years
-Lead in Spring One Acts past two years
-Lead in show about gun awareness
-Inducted into International Thespian Society
-Member of Quizbowl
-MUN member (attended a few collegiate conferences)
-Interact Club
-Volunteer at Animal Shelter+Senior center (about 100 hours)
-TA for freshman biology class

I also plan on raising money and working at a school for under privileged kids. I have already raised $125 but I plan on raising a few hundred more. I also got into a STEM academy at a college nearby. I am just really worried because I feel like I am doing about as much as I can, but 3 Bs would really bum me out. Help!
