Very sorry about your results. As for gap year v your home college depends on your goals and how much an us school will help. What about Europe or Canada? Also there are still schools with admissions in the US. Also if your first language is not English 1900 is a great score
It just amazes me that people actually think that 60k is a reasonable amount to pay for anyone no matter how rich. The 0 EFC are often better off than the 100k family at the top colleges, the process is frustrating for everyone. Yet we are all begging and pleading to get into Stanford. In state is no better at 20-30k. As for international with all due respect to the OP, all colleges except for those who discriminate based on race are getting federal funding so there really is no such thing as a private university, US tax dollars pay for some part of almost every US school most people just do not realize it
