You could also speak to your high school about getting the Seal of Biliteracy (formalized by the State of Rhode Island):

The test itself is fairly intense, involving both written and spoken aspects.
I do know from other ESL students at our high school (different language), that while they were absolutely fluent in conversational language and had extensive vocabulary, they never had taken formal, secondary education classes in their native language. Them taking formal HS classes in their native language was not at all guaranteed top grades, and they did have to truly apply themselves (even “unlearn” a few things).
This might be different in your case, but it can’t hurt to take a practice AP exam to see if you need to polish up on anything.
