Can I go Ivy League School with GED? (for international student)

Hi! I’m in sophomore year in U.S private high school, and I’m international student from Korea.
I’d like to go back to Korea for 1 year and to prepare GED test with highly score in SAT, SAT2, APs, TOEFL.
If I get almost 1600 on SAT, more than 2 SAT2, more than 5 APs (with 4-5 score) and more than 100 on TOEFL test, Can I enrolled UC Berkeley, and IVY League Schools?
(I will definitely prepare my essay and perfect extra curricular and perfect volunteer.)

It’s vanishingly unlikely, but not impossible. But there is no such thing as “perfect extracurricular” or “perfect volunteer.”

Why would you want to do this? It seems like a plan which is quite unlikely to be successful.

Why not just finish high school either where you are now, or in a high school in Korea?

Your odds of completing that plan successfully and getting into a top school are even lower than if you just finish high school the usual way.

Why can’t you get a normal high school diploma?
Colleges would not be able to assess your grades.
I think they might worry about fraud if they saw an international student with GED but 1600 SAT

Top colleges don’t like the GED, which represents only basic requirements for secondary graduation.
Can’t you graduate from your current school?
Btw, top 25 universities and LACs want excellence in extra curricular activities.

You do not want to take the GED exam series. It is designed for US students. I teach GED exam prep. If your writing here is a good sample of your English writing, you are nowhere near ready to take those tests.

Your best choices are:
a) Stay in high school in the US and graduate here. Take the TOEFL, ACT/SAT when you are ready for them. If your ESOL teachers think you should spend more time in Academic English classes to get ready for college work, do that too.
b) Finish high school in Korea and graduate with a Korean diploma. Take some extra English classes to get ready for the TOEFL. If your English teachers recommend it, enroll in an intensive English program to get ready for college work, and then apply to collge in the US.
