How do colleges calculate Rigor of high school

<p>How do colleges(ivy leagues and colleges around the top 20's and 30's), calculate the rigor of your high school? I go to a high school(11th and 12th grades only) where everybody is obligated to take 3 college classes. the most that can be taken are 4. The school also tends to squeeze in 3 AP classes for both junior and senior year. There are only 200 students and they must sustain a gpa above 3.0. How would a school like this one be viewed by prestigious colleges?</p>
