Am I on the Right Track?

hi all,
i apologize in advance if this a stupid post! and thank you for reading I appreciate it

i’m a freshman and my dream school is probably Northwestern(i know it’s a stretch) and I really want to go into the medical field in the future. am i on the right track?

my current courseload is:

eng 9 (required, everyone takes the same course)
modern world history (required, everyone takes the same course)
french 1
algebra 2
PE Sports (cross country first semester and now i’m on the swim team)
orchestra

i struggled to manage my time and make an effort to get help (i know that wasn’t very smart of me) and did very poorly in algebra 2 honors so I dropped to algebra 2 regular this semester but I am currently getting an A in the class… I also have the opportunity to replace the bad grade on my transcripts with an online course that I am taking right now

At the moment, my GPA is 4.0

I also plan to take biology over summer.

Current Extracurricular Activities include:

-orchestra
-swim team (jv–i can probably move up to varsity in the next few weeks)
-destination imagination
-newspaper
-ASB
-piano

Leadership:
concertmaster (first chair) of the orchestra

class treasurer

I know that I should definitely volunteer more…

What else should I do?

thanksss
