What can I do to increase my chances of getting accepted into an Ivy League schoool?

I’m a sophomore currently. Do any of you have advice on what classes I should take and what else I can do to spice up my application? Would be greatly appreciated. I know my resume is not really that much and I am aiming sort of high. So what can I do to help my chancing of ivy league acceptance for the second half of sophomore year and next year?

White female, lower class, immigrant (Russia), currently living in orange county NY
High school GPA since freshman year is 96 but I will definitely get it up to a 98 (on a 100 scale. Honors/AP are weighted in my school)
I am currently in:
Language (Italian)
AP World hist
English Honors
Science Research
Geometry (reg)
Bio Honors
Orchestra
Junior year I will most likely take:
Language (Italian)
APUSH
Science Research
AP Environmental science
Chem honors
Alg 2 honors
AP English Lang
Orchestra
Senior year I may take:
AP bio
AP Italian
Science Research
AP Euro
(not sure of other classes since it’s far away)

I will take a psychology class at a community college in 2018 to prepare for the AP exam since AP psych is not offered at my
school

I will take the World History subject test this year and I have not decided which other ones I will take

I volunteer at my town court and will soon volunteer in a hospital. I am currently working on independent research on Lyme disease. I am also taking a 10 day law program during the summer at Stanford (called the Envision Law & Trial Program). Summer of junior year I will volunteer abroad possibly in Nepal or Thailand. I am part of 2 clubs, SADD and mock trial, no leadership positions right now. I have been running track for a few years. I have not taken the SAT yet but I am practicing. I know it’s not much, but that’s why I’m asking; so I can get suggestions. Thanks!

@Katee114 Привет! (I know few in russian!)

Your course catalog is on par for an ivy league candidate. Honestly what will boost your chance the greatest is to do really good on SAT or ACT. Also get GPA as high as possible. Right now as a sophomore, just focus on school get the best grades you can you’ll be fine! If you really want, study for the SAT on Khan Academy a little (it will also help your english/math skills) as SAT is based off of 8th-10th math. But like I said focus on your schoolwork and study up you r on the right path

@kate114 also you should volunteer abroad in Fiji, I live in America but I am Fijian its a great place where you can do great volunteer work (and enjoy great vacation weather)

Closing thread as the OP has started a new one.
