Read up on Texas' 10% law that gives the top 10% of students in each high school automatic admission to one of the states schools.
It almost feels like I shouldn't be posting in this thread since USA and Canada have radically different education systems. This sounds really really weird.
In Canada, getting into university is about 99% based on when you applied. My local university has a 70% required average between certain classes (math, physics, etc) to get into science, and what you do is apply using your grade 12 second semester marks from the first report card. Each semester has 2 report cards, so the first one comes out around the end of March I believe. You show them you have an 70% or greater average at this time, they let you in, and you pay a deposit so they hold your spot. I think I paid $40 to reserve my spot. Once you finish high school, you give the university an official transcript to verify that you passed and you still have the required 70% average. Once that's all done, you pay an extra registration fee to verify that you still want the spot and you will be attending. If you failed or your average dropped to only 65%, you lose your despot and your spot is open again. From this point, I think they actually start to look at the grades of the people applying. I don't really know since I've never been rejected at the first stage.
When I went back to school a second time, this time for engineering, I applied in November of the year before the year I was applying to. I was probably the first person to apply for it, so I got in right away. No questions asked, no essay required. I think the only race question on the application was my Indian treaty status. I'm not a native, so I get grouped with whites, blacks, Asians, hispanics, etc. Even with the special treatment for native Indians, electrical engineering has exactly 0 Indians.

Overall this system seems to work. It doesn't even differentiate between honors students and marginally good students. All that matters is that you cared enough to apply as soon as possible.
