It is a good thing to be able to enter ESL immediately, because many ESL classes are a waste of time. You can just read more grammar books yourself. In fact, not having AP classes will not have a bad impact on you, because you have just come to the United States. When you apply for college, the admissions people will consider this. Your class schedule looks good for a new immigrant. Learning Spanish will be of great help to you because there are many Hispanics in the United States.
For the SAT, you can actually study by yourself, but this method is too risky for you. (Nothing malicious, I'm just saying your time is limited and you're a new immigrant). I suggest you sign up and take SAT classes. The school will not have SAT classes. You have to pay your own money to find some good institutions outside to take them. Some are also very good, but they are more expensive (but they are definitely worth it, because SAT scores are very important, as are gpa and extracurricular activities. Very important)
Don’t worry about not knowing anyone. Believe in yourself and encourage yourself. Living in a completely unfamiliar country is not easy anymore.
Here are some suggestions for you in the next two years:
1. Your math is your advantage. You should communicate with many math teachers, which will be very helpful in writing college recommendation letters in the future
2. If you don’t understand, just bother the English teacher as much as possible. I’m not lying. Teachers in the United States are very happy to help students, especially immigrants
3. The advantage of the United States is that there are many libraries, so you should make good use of the resources, read more, and communicate with foreigners
4. If you encounter any problems, you can communicate with your counselor at any time. This is their job
Believe me, it is not as difficult as you think
I have been there. I was there four years ago I came to San Francisco in the United States. I am now seventeen years old and am applying for college
Really, it is not as difficult as you think
