Admission officials at hyper-selective colleges like Brown are well aware that not all high schools are created equal. They realize that at challenging schools like yours, the workload can be very heavy, and A's are not easily earned. So the admission folks typically allot some extra wiggle room to applicants who hail from the most competitive private (and public) schools.
Moreover, the Ivy League colleges usually attract many applicants from these rigorous high schools which means that it can be pretty easy to get at least a ballpark sense of your admission odds at Brown, based on the experiences of your predecessors. Your high school probably uses “Naviance" or some other online tool to track college outcomes. Thus you can check the Naviance data to see how many students with a rank and/or GPA like yours have applied to Brown over the past five or so years and how they fared. Keep in mind, however, that Naviance will NOT tell you if admitted candidates were recruited athletes, underrepresented minority students, and legacies, or if they had any other sort of major “hook" that would spur the admissions committee to overlook a sub-par rank or GPA. So you should also talk with your guidance counselor when school resumes in the fall to ask how your current stats compare to those of former Brown hopefuls who had the same hooks … or lack thereof … that you have.
In addition, because the vast majority of Brown aspirants are strong students with excellent test scores, it takes more than just big “numbers" to get past the outer gates. If you don't have one of the aforementioned hooks, you must ask yourself what else you will contribute to the college you attend. For instance, do you have exceptional talent in music or the arts? Do you come from an uncommon background? Are you the first in your family to attend college? Without anything special in your overall profile, you probably won't get the good news from Brown that you want, especially if your grades put you outside of the first two deciles, even at a demanding private high school. And, sadly, “special" at the exalted Ivy level doesn't just mean “good." Spanish Club treasurers and orchestra section leaders are routinely passed over in favor of student body presidents and musicians who played at Carnegie Hall. And each year the Ivies turn away thousands of applicants who are just as qualified as those who got in. A Harvard admissions dean once conceded that he could set aside all the applications that came from accepted students and then select an equally impressive class from the “reject pile."
So your next step is to ask yourself how you will stand out from the crowd at application time, and then talk to your counselor in September to ask if similar Brown candidates from your school were accepted in the recent past.
Although admission officials will definitely evaluate you in the context of your own school community and won't be comparing you head-to-head with the salutatorian from the public school on the other side of town, it's important to understand that many seniors aiming for the Ivies and their ilk also attend rigorous private schools and yet land in the top tenth of their classes in spite of it. So your job as you continue through the admissions maze is to try to use your applications—and your essays especially—to show admission committees what you will bring to campus, even if it's not a tip-top rank.
Good luck to you and thank you for your kind words about “The Dean."
