I will be moving to the U.S in three months and I won't be able to attend college until I get my residency, which I will hopefully obtain in December. Unfortunately, I was unable to take any APs during my high school years because they are awfully expensive here (about US 500.) Leaving that aside, I do have a strong high school record.
My question is, if I take some AP classes and retake the SATs (along with the Subject Tests required by some admissions department,) could I apply as a freshman for Fall of 2016? Or are the APs not that significant? If so, what are some other aspects that I should focus on instead?
In other words, is it a good idea to take a gap year and strengthen my application?
I'm considering Vassar as a number one choice, so I'm trying to prepare my application according to their standards.
