If you finished your full secondary education in your country, and arrived here with all of your academic records, then there was no need whatsoever to enroll in high school here. Many school districts wouldn’t permit it at all. That you are considering taking the GED exam series makes me wonder if you did finish high school. You won’t be eligible for federal financial aid without a full high school diploma (from anywhere in the world) or the GED.
Did you finish your secondary education? Do you have full records of your foreign schooling? Have they been formally evaluated by an organization such as https://www.wes.org/ ?
If you didn’t finish high school in your home country, even though some of your classes are boring right now, it is better for you to complete a full high school diploma here. I teach GED exam preparation. The exam series is not easy - especially for international students. There is a lot of vocabulary and cultural material specific to the US in the English exam that you probably don’t know yet. In addition, the GED is only a minimum certification. A full NYS regents diploma is more than the bare minimum and will give you more options. You should be talking with your current teachers about taking honors classes next year and starting to create the relationships that will get you better letters of recommendation.
If you take a gap year, what would you do besides GED prep? What is your visa status? Are you eligible to get a job?
