SAT

Hello Naman Gowda,
It is very nice and interesting to know that you want to join United States Air Force Academy. But I am afraid, like the Indian Air Force Academy at Dindigul near Hyderabad, admissions to United States Air Force Academy in Colorado are also restricted to the citizens of that country, United States of America, as a result I am sure you will not be eligible unless you are a US citizen and still studying in India. Else you are an x Indian in US with US citizenship. I am attaching a link which will give you all the required information about eligibility and how to get admission in this coveted United States Air Force Academy.

The SAT is a globally recognized college admission test, administered by the College Board, that lets high school students show colleges what they know and how well they can apply that knowledge. Most students take the SAT in 11th or 12th Grade, some even earlier, in 10th Grade. Almost all colleges and universities in the United States, and many colleges worldwide, use the SAT to make admission decisions. Topics Tested
The SAT tests skills taught in high school classrooms: reading, writing and math. A student's knowledge and skills in these subjects are important for success in college and beyond. The critical reading section includes reading passages and sentence completions. The writing section includes a short essay and multiple-choice questions on identifying errors and improving grammar and usage. The mathematics section includes topics like arithmetic operations, algebra, geometry, statistics and probability. Exam Duration
The SAT is a fairly long exam 3 hours and 45 minutes in duration, and made up of 10 sections:
One 25-minute essay
Six 25-minute sections (mathematics, critical reading and writing)
Two 20-minute sections (mathematics, critical reading and writing)
One 10-minute multiple-choice writing section
Scoring
Each section of the SAT (critical reading, mathematics and writing) is scored on a 200-800 point scale, for a possible maximum total of 2400. Students also get two sub scores on the writing section: a multiple-choice score from 20 to 80, and an essay score from 2 to 12.
