Do universities look at what high school you went to?

Well I used to be from a different district in my county, and my mom decided to move me districts after middle school because she said that the school district really close to where i live (different city but really close by, like 5 min) is a much better academically. And i have been at this school for two years now and its been proven to me that the schools are totally different. Way harder here than at my old one. My friends from the other district are all in higher classes than me an in AP and HONORS classes and for my junior i am not taking any of those higher classes. And whats bugging me is that most of them have a chance to go to a university because of their easy grades and i won't be. Trust me guys, i know its like your saying hey their smarter than you, but NO we are at the sane level. Our school gets a lot of transfers from other cities and students from the previous city i went to school their and they also say that it is 10x harder at this school than their previous one. So do Universities take that into account? because i honestly don't think its fair...
