This is not a very big problem considering the scenario today. You will get lots of information about the studies in US. There are SAT and ACT exams conducted there which are considered for the entrance to colleges. My cousin, who was from Delhi went to US for her higher education and she really prepared hard to take admission there and she also got a great help from the guide application boot camp. I would recommend the same sources for you to get prepared. The people who wrote it were admissions officers at an Ivy League school in America.
