Can I still get into a top school college? - Issues with classes - PLEASE HELP!

I would suggest you reread your other thread about this issue.

Do I need to take US History to go to a top school? - HELP ME PLEASE

At my school, you take APUSH in 10th grade, and due to scheduling conflicts, I could not take the course. My school’s college counselor stressed that it would be near impossible for me to get into a top school without taking us history. I took an online honors history course the summer after 10th grade. Now, I am a rising senior and I was planning on taking a dual enrollment online us history course, but now I’m thinking it might be a better use of my time to take a class like linear algebra or python instead. For context, I want to study ecology/mathematics and my top schools are harvard, cmu, yale and brown. PLEASE HELP!!! THANK YOU!
